What is a 30ml glass bottle used for?

Face serums, facial oils, hair serums and beard oils. It is the most common full size for serums.

How many drops are in a 30ml bottle?

About 600 drops, at roughly 20 drops per ml. Dropper size and oil thickness change the count.

Does the 30ml bottle come with a dropper?

No, it is the bottle only. Add any 18mm dropper, pump or cap separately.

Which dropper fits a 30ml bottle?

Our 18mm glass dropper sized for 30ml bottles, or the 18mm euro dropper insert.

Is amber or clear better for a vitamin C serum?

Amber, or black. Vitamin C breaks down in light, so avoid clear glass.

What is the difference between frosted and clear glass?

Frosted glass has a matte, premium finish. Amber frosted keeps amber's UV protection; clear frosted offers little.

Is there a minimum order for 30ml bottles?

No. Buy one bottle to test or thousands for production.

Can I mix colours for a wholesale price?

Yes. All colours of this size count together toward the next price slab.

Is RENTRASPA a manufacturer?

No. We are an importer and wholesaler, holding stock in Chennai and shipping across India.

Product Description

This 30ml glass bottle has an 18mm neck and is sold as the bottle only. Pick from seven colours: amber, amber frosted, clear, clear frosted, blue, green and black. Then fit a glass dropper, euro dropper, pump or cap. 30ml is the most common full size for face serums and facial oils.

Why the 30ml glass bottle is the serum standard

Shoppers expect a serum to come in 30ml. A 30ml glass bottle gives a premium feel without a high fill cost. It holds about 600 drops. The 18mm 30ml amber bottle is one of our fastest-moving items. Brands choose it for consistent glass quality at a fair price.

Amber	Light-sensitive oils, actives and essential oils. Blocks most UV light.
