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: they are sold without a cap, so you add the 18 mm cap your product needs. Choose a glass dropper, euro dropper, spray pump, lotion pump or screw cap from Bottles & Caps and add it to the same order. Prices on this page are for the glass bottle only.
-
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.
-
Choose the glass dropper with the same size as the bottle, from 5 ml to 100 ml. The pipette length is cut for that bottle, so a 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.
-
5 ml, 10 ml, 15 ml, 30 ml, 50 ml and 100 ml, each in seven colours: amber, amber frosted, clear, clear frosted, blue, green and black. 30 ml is the usual serum and face-oil size, 5–15 ml suits essential oils and perfume minis, and the 100 ml glass bottle suits toners, hair oils and body oils.
-
Amber for anything light-sensitive, frosted or clear to show the product, and blue, green or black for the look. Amber glass bottles filter most UV light, which protects essential oils and actives. Black blocks almost all light. Frosted glass gives a soft matte finish and hides fingerprints.
-
Each product page lists the price per piece for every colour, and it steps down as the quantity rises. All seven colours of one size count together towards the next price step, so you can mix colours and still reach bulk pricing. The bottle and the cap are priced separately, so you pay only for the cap you need.
-
No: order a single bottle, or thousands. Mix sizes and colours freely. Your logo printed on the glass starts at just 1,000 pieces. For large runs, WhatsApp +91 75500 42423 with the sizes and quantities.
-
In-stock sizes leave Chennai within 3 working days; sizes marked Pre-order are booked now and ship when the next shipment lands. Each size and colour shows its own stock on the product page. WhatsApp +91 75500 42423 for the expected date of a pre-order size.
-
Yes: the cap decides the use. A euro dropper suits essential oils, a spray pump suits perfume and face mists, a glass dropper suits serums and face oils, and a lotion pump suits lotions and body oils. Use amber or black glass for light-sensitive oils and actives.
-
They ship straight from the factory cartons, not pre-washed or sterilised. Wash bottles in warm water with a mild detergent, rinse, and air-dry fully before filling. A rinse with 70% isopropyl alcohol is a quick way to sanitise the glass. Wash caps separately and never boil pumps or droppers.
