About RENTRASPA

Who is RENTRASPA?

RENTRASPA is a Chennai-based importer and wholesaler of cosmetic glass packaging — glass bottles, jars and vials with matched droppers, pumps, sprayers, roll-ons and caps — for skincare, cosmetics, hair care, perfume, wellness and Ayurveda brands. The business is owned by elements5 and has traded since 2015. We sell across India on this website and on WhatsApp, to first-time founders, salons, formulators, contract manufacturers and established brands.

Are you a manufacturer?

No — we are importers and wholesalers of glass packaging; we don't make glass or cosmetics. Glass factories work at minimum orders of 10,000 pieces or more per design — far more than most brands need, especially at launch. We are the bridge between the two: we buy from established overseas glass suppliers in the volumes they need, keep fast-moving bottles, jars and closures as ready stock in Chennai, and sell to you from a single piece. The factories get their volume, and you get the quantity you need.

A useful check when you compare suppliers: anyone who offers you fewer than 10,000 pieces of a design is not the manufacturer, whatever they call themselves — they are a wholesaler or trader, like us.

Is RENTRASPA a registered business?

Yes. RENTRASPA is a brand of elements5, a GST-registered business in Tamil Nadu trading since 2015, with a showroom in Thiruvanmiyur, Chennai. Every order comes with a GST invoice, and you can read what customers say on our reviews page.

Do you work with small and new brands?

Yes — most of our customers are startups, indie skincare brands, salons and small D2C founders. You can buy a few pieces to test a formula, then order in bulk when you launch. We also supply contract manufacturers and established brands.

Do you offer white-label or private-label products?

No. We supply empty packaging only — we don't formulate, fill or make cosmetic products, and we don't offer white-label or private-label manufacturing. What we do offer is decoration of the containers with your brand, done to order from 1,000 pieces (see customisation).

Ordering, samples and minimums

What is your minimum order quantity (MOQ)?

There is no minimum for ready-stock items — you can order a single piece. Minimums apply only to items ordered in for you: customised (printed, painted or frosted) containers from 1,000 pieces, custom closures from 5,000 pieces, and UV coating from 10,000 pieces.

Can I order samples before placing a bulk order?

Yes — buy one piece, or a few, straight from the product page. Use it to check the glass, the size, how the closure works with your product and how your label looks, and test your formula in it before you commit. We don't issue tech or spec sheets, so a sample piece is also the way to check the neck, fit and dimensions yourself.

Can I mix sizes, colours and shapes in one order?

Yes. One order can mix any sizes, colours, shapes and closures. For bulk quotes, containers and closures are priced as separate lines, each by its own quantity.

How do I place an order?

For smaller quantities, order on this website and pay at checkout. For 500 pieces or more, or anything customised, WhatsApp us the items and quantities: we confirm the price and stock, raise a proforma invoice, you pay the advance, and we dispatch. A purchase order is welcome but not required.

Is the item I want in stock?

Fast-moving bottles, jars and closures are held as ready stock in Chennai. For larger quantities, WhatsApp us the item and quantity and we'll check. Anything we don't hold can usually be ordered in for you as a made-to-order item, with a lead time of 45–60 days.

Do you supply wholesale and bulk orders?

Yes. Brands, salons and contract manufacturers usually test a sample piece, then order in bulk. Quantity pricing is shown on every product page, and from 500 pieces we quote on WhatsApp. See how bulk supply works on our bulk supplier page.

Can I reorder the same items or the same customised design?

Yes — we keep a record of your items and your customisation, so reorders are quick. Custom bottles and custom caps can be ordered in different quantities: for example, 1,000 printed bottles with 5,000 custom caps, then more bottles 1,000 at a time using the caps you already hold.

Do you have a catalogue?

Yes — download the PDF catalogues from our catalogue page, or ask on WhatsApp and we'll send the latest one. This website always shows the current range.

Can I see real photos or videos before I buy?

Yes. Ask on WhatsApp and we'll share photos and videos of the actual bottle, jar or closure.

Prices, payment and invoices

How much do your bottles and jars cost?

Every product page shows the price per piece and how it steps down as the quantity rises — from single pieces through mid-size to bulk quantities. From 500 pieces, WhatsApp +91 75500 42423 with the item and quantity for a quote. We don't publish a bulk price list, because bulk prices depend on the exact item, quantity and decoration.

Why buy from RENTRASPA instead of importing from Alibaba or a cheaper supplier?

No minimum, no import paperwork, and someone in India to call. Glass factories usually need 10,000 pieces or more per design; we sell from one piece. We consolidate orders from many customers into bulk shipments and handle freight, customs and duty, so the price you see already covers them and comes with a GST invoice. Stock is in Chennai and dispatched within 3 working days. Bottles come with closures matched to them — the closure is where cheap packaging most often fails. And if there's a problem, we're here in India to sort it out.

What are your payment terms?

Every order is 100% advance, whatever its size and whether or not it is customised.

On the website you pay at checkout. For anything ordered through WhatsApp we raise a proforma invoice and the full amount is paid against it. There are no split or staged payment terms.

How can I pay?

On the website, pay at checkout. For WhatsApp orders we send a proforma invoice, and you pay the advance by bank transfer or UPI.

Do you offer credit?

No — our standard terms are advance payment only.

When is a pre-order confirmed, and can I cancel it?

A pre-order is confirmed only once we receive your advance, and that advance is non-refundable. A pre-order is anything we don't supply from ready stock in Chennai: customised containers or closures, made-to-order items, and quantities we import or procure specifically for you. Until the advance reaches us, prices, stock and production slots are not reserved. Once it is paid, we place the order with our suppliers on your behalf, so we can't refund the advance if you cancel, reduce or change the order. For standard (non-customised) items, we will try to sell the stock to another customer within 90 days; if we do, we refund your advance less a 15% handling charge on the cancelled order value and any price reduction needed to sell it, once the new buyer has paid. If we are unable to supply your pre-order, we refund everything you have paid, and goods that arrive damaged or defective are covered by our refund policy. Ready-stock orders can still be cancelled for a refund until they are shipped.

Do I get a GST invoice, and how is shipping charged?

Every order comes with a GST invoice. Freight is charged on the order and depends on the destination, weight and quantity; the website shows it at checkout, and our WhatsApp quotes include it.

Customisation and branding

Can you print my brand on the bottles and jars?

Yes — screen printing, painting in Pantone colours (including gradients), frosting, hot stamping from 1,000 pieces, and UV coating from 10,000 pieces. Decoration is done to order, on bottles and jars from our range, and takes 45–60 days from sample approval. Customised orders are on 100% advance when you book. Wooden lids can also be etched with your logo — ask on WhatsApp for the minimum. See customised cosmetic packaging.

Can I get custom caps, pumps or droppers?

Yes — custom closure colours and printing from 5,000 pieces, on 100% advance when you book. Below that, we supply our standard closures. Custom closures and custom containers can be ordered in different quantities.

How long does customisation take?

45–60 days from sample approval. Customised and made-to-order items are produced and imported for your order, so we can't offer rush orders — plan your launch around this lead time. Ready-stock items are dispatched within 3 working days.

Is there an extra charge for customisation?

Yes. Printing, painting, frosting, stamping and UV coating add a cost per piece that depends on the technique, the number of colours and the quantity. WhatsApp your artwork and quantity for a quote.

Can you design my packaging or labels?

No — we don't design artwork or labels, and we don't apply labels. For printing or painting, send your print-ready design files and colour references (Pantone numbers). We'll help you choose the container, closure and decoration technique: WhatsApp a photo of your product or artwork.

Can you make custom glass bottles in your own shape or mould?

Yes, for larger projects. Our glass suppliers can make a private mould for your own bottle or jar design, and the mould can carry your logo, embossed right into the glass. That covers custom shapes, custom sizes and custom neck sizes. There's a one-time tooling charge, and it takes longer than buying from our stock, so custom moulds make sense when you're ordering at scale. WhatsApp us a drawing or a reference photo of the custom shape you have in mind, plus the quantity, and we'll tell you what's possible. Smaller run? We decorate existing bottles and jars from our range (logo printing starts at 1,000 pieces), or have a look at the luxury families for a distinctive look that's available now.

Can I buy plain bottles and decorate them myself?

Yes. Every item is sold plain, so you can label, print or brand it yourself or with a local printer.

Dispatch, delivery and damages

How fast do you dispatch?

In-stock orders are dispatched within 3 working days of payment, from Chennai. Made-to-order and customised items take 45–60 days (for customised items, from sample approval).

Do you deliver across India, and how long does delivery take?

Yes — to every state, metros and smaller towns alike, through courier partners. Transit time depends on your location and the courier. If a delivery is running late, WhatsApp your order number and we'll check and chase it.

Do you ship outside India?

We mainly serve India, but international enquiries are welcome. WhatsApp +91 75500 42423 with the items, quantities and destination country.

How is glass packed for shipping?

In multi-layer protective packing, and breakage is rare. If something does arrive broken, see the next question.

What if something arrives broken?

We replace products damaged in transit if you report it within 2 days of receipt. WhatsApp +91 75500 42423 with your order number and photos of the outer box and the broken pieces.

Can I return items I no longer need?

Customised and made-to-order items can't be returned once produced for you. Ready-stock items can be returned if you call or WhatsApp us within 2 days of receipt, and exchanges are considered case by case.

Will the containers leak during shipping or travel?

Our caps (with inner plugs or wads) and pumps close securely. Sample bottles from our stock are fill-and-invert tested — filled, closed and turned upside down to check for leaks. For shipping or travel, keep bottles upright, add a shrink band or tape, and test your own formula with a sample first.

Bottles, jars, glass and closures

What types of cosmetic packaging do you sell?

Glass containers, the closures that go on them, and matched sets of both. Containers: dropper and serum bottles, lotion and pump bottles, spray bottles, perfume bottles, roll-on bottles, essential oil bottles, cream jars, lip balm pots and vials. Closures: pipette droppers, euro droppers, lotion pumps, spray pumps and caps — see closures. For a coordinated range, the luxury families pair bottles and jars that share one cap design.

What sizes do you offer?

Bottles and vials from 1ml to 150ml, and jars from 5g to 250g. The most common sizes in the range are 10ml, 30ml, 50ml and 100ml bottles and 30g and 50g jars. Jars are sized by the weight of product they hold, from small lip balm pots to 100g–250g jars for scrubs and powders. Every product page lists the sizes that design comes in.

Do bottles come with closures?

Yes — every bottle ships with its closure (dropper, pump, sprayer, roll-on or cap) unless the listing says otherwise. Spare 18mm pipette droppers, euro droppers, spray pumps and lotion pumps are also sold separately under closures.

Which container should I use for my product?

Match the closure to how thick the product is and how it's used:

Not sure? WhatsApp a photo of your product and we'll suggest a bottle and closure.

Which glass colour should I choose?

Amber filters most UV light, so it suits light-sensitive oils, serums and actives. Blue and green glass filter part of it and are often chosen for the look; black glass blocks nearly all light; clear and frosted glass show the product but give little light protection, so keep light-sensitive formulas in a carton or out of the sun. We stock amber, clear, frosted, blue, green, black and painted glass, and other colours can be painted to order from 1,000 pieces.

What glass are your bottles made of? Is it borosilicate?

Our bottles and jars are thick cosmetic-grade glass; only our small sample vials are borosilicate. Glass is non-reactive, so it suits essential oils, serums, creams and alcohol-based perfumes — but always test your own formula in a sample piece. Our containers are cosmetic-grade packaging and not recommended for food.

Do you sell plastic packaging or airless bottles?

No. RENTRASPA™ sells glass packaging only: glass bottles and jars for cosmetics. The closures on them, caps, pumps and droppers, can be plastic, metal or glass, depending on the design. If your product really needs plastic packaging or airless bottles, just ask on WhatsApp. We know a few good suppliers and will point you to one.

What is a euro dropper?

A euro dropper is a drip insert (an orifice reducer) that sits in the bottle's neck under a screw cap, so the bottle pours drop by drop. It is not a pipette and rubber bulb. Euro droppers suit essential oils and other thin oils; thicker serums and face oils are easier with a pipette dropper. See essential oil bottles.

Do you sell crimp-neck perfume bottles?

No — our perfume and spray bottles have screw necks, and each comes with a screw-on fine-mist pump that you fit after filling. No crimping machine is needed, and screw-neck bottles can be washed and refilled.

Do you have child-resistant closures?

Only on our 9g child-proof glass lip balm jars, in white square and black round. We don't offer child-resistant caps on dropper bottles or other items.

Do you supply boxes, cartons or labels?

No — we supply glass containers and closures only: no boxes, cartons, inserts or labels. A sample piece is the easiest way to give your box or label printer the exact size.

Are your glass containers recyclable?

Yes — glass is fully recyclable, and our bottles and jars can be washed and reused many times. Replace pumps and droppers when they wear out.

Do you supply pharmaceutical brands?

We mainly serve cosmetic, personal-care and wellness brands. Our containers are cosmetic-grade packaging; pharma and nutraceutical buyers are welcome to order, but please check that cosmetic-grade glass meets your product's regulatory requirements first.

Cleaning, filling and storage

Are the bottles sterilised? Should I sterilise them before filling?

Yes, wash and sanitise before filling — the containers ship straight from the factory cartons and are not pre-washed or sterilised. Wash glass and closures in warm water with a mild detergent, rinse, sanitise with 70% isopropyl alcohol and let everything dry fully. Don't boil pumps, droppers or plastic caps. Clean containers matter for your product's safety, stability and shelf life.

How should I store glass containers before filling?

In a clean, dry place away from direct sunlight and extreme temperatures, covered until you're ready to wash and fill them.
