Glass Bottles Only — 18mm Neck, 5ml to 100ml, Add Your Own Cap

These are empty glass bottles with a standard 18 mm neck, sold without a cap, so you choose the bottle and the cap separately. Pick 10 ml, 15 ml, 30 ml, 50 ml or 100 ml, each in amber, amber frosted, clear, clear frosted, blue, green or black glass. Then add any 18 mm glass dropper, euro dropper, spray pump, lotion pump or cap from our bottle caps range. These small glass bottles sell from one piece; all colours of one size count together towards the next price step.

    Frequently Asked Questions

    • No. We sell these empty glass bottles bare, with no caps or lids, and you add the 18 mm cap you want. Usually that's a glass dropper, a euro dropper, a spray pump for perfume, a lotion pump or just a screw cap, from our Bottles & Caps page, in the same cart. The price here is the glass bottle alone.
    • Every 18 mm cap on RENTRASPA fits every bottle here. That covers glass droppers, euro dropper inserts with plastic or metal screw caps, mist spray pumps and lotion pumps. Pick the cap colour and finish on each cap's product page: black, white, gold, silver and more.
    • The neck is 18 mm on all of them, so go by size: a 30 ml bottle takes the 30 ml glass dropper, and so on, from the 5 ml up to the 100 ml glass bottle. We get asked this a lot on WhatsApp. The glass pipette is cut to one length, so a 30 ml dropper knocks the base of a 15 ml bottle, and in a 50 ml bottle it stops short of the last bit of oil.
    • We have six: 5 ml, 10 ml, 15 ml, 30 ml, 50 ml and 100 ml, in amber, amber frosted, clear, clear frosted, blue, green and black. 30 ml is where most serums and face oils end up, usually with a glass dropper. Essential oils and perfume minis tend to go 5 to 15 ml, and our 100 ml glass bottle gets used for toners, hair oil and body oil.
    • Amber glass bottles are what you want for anything light spoils, say essential oils, vitamin C, retinol. Amber blocks most UV. Black blocks nearly all. Blue and green, to be honest, are mostly a looks thing. Clear and frosted glass show off what's inside; frosted has that soft matte feel and doesn't show fingerprints.
    • Every small glass bottle on this page is well under ₹100 each, and the price per piece drops as you buy more. Handy bit: all the colours of one size count together for the price step, so amber and frosted mixed still get the bulk rate. Caps are a separate line, so you're not paying for bottle caps you don't need.
    • Right here, and there's no minimum: one bottle is fine, and so are a few thousand. Mix sizes and colours however you like. Your logo printed on the glass starts at 1,000 pieces. Planning a big run? WhatsApp +91 75500 42423 and we'll sort it out.
    • If it's in stock, we pack it and it leaves Chennai within 3 working days. Pre-order sizes go out when our next shipment lands; each colour shows its own stock. After it leaves Chennai, it's down to your city and the courier. Need a date for a pre-order size? WhatsApp +91 75500 42423.
    • Yes. What the bottle is for depends on the cap you put on it. Our customers use a euro dropper for essential oils, a spray pump for perfume or a face mist, a glass dropper for serums and face oils, and a lotion pump for lotions. Oil that goes off in light? Put it in amber or black glass.
    • Warm soapy water first, then a rinse, then a wipe inside with 70% isopropyl alcohol, and leave them to dry fully before essential oils or serums go in. They come straight from factory cartons, so they aren't sterilised yet. Boiling the glass for 10 minutes works too; just let it cool slowly or it may crack. Don't boil pumps or a dropper, though.

    Choose your cap

    Cap Fits Best for
    Glass dropper (pipette, metal ring, silicone teat) 5 ml to 100 ml: pick the pipette that matches the bottle size Serums, face oils, hair oils
    Euro dropper insert with screw cap All sizes Essential oils, one drop at a time, sealed for travel
    Mist spray pump All sizes Perfume, toners, face mists
    Lotion pump All sizes Lotions, gels, body oils
    Screw cap only (plastic or metal) All sizes Storage, refills, sealed minis

    The pipette must match the bottle. A glass dropper made for a 30 ml bottle is too long for a 15 ml bottle and too short to reach the bottom of a 50 ml one, so choose the same size on both.

    Glass colour. Amber filters most UV light and protects essential oils, vitamin C and retinol. Black blocks almost all light. Blue and green filter part of the light and are chosen for the look. Clear and frosted glass show the product and suit stable formulas or products sold in a carton.

    Why buy the bottle on its own. Run one bottle across several products with different caps, restock bottles without paying for caps you already hold, switch a range from dropper to pump without changing bottles, or use caps you already have. Every 18 mm cap on the site fits every bottle here.
