The 30ml Amber Boston Glass Bottle without cap is the ideal choice for formulas that will be fitted with a pipette, dropper or spray closure. The smaller size pairs perfectly with concentrated essential oils, aromatherapy blends, facial toners, serums and other small-dose natural products.
Why Amber Glass?
Amber borosilicate glass filters ultraviolet light, which degrades sensitive active ingredients — especially essential oils, plant extracts and oxygen-sensitive formulas. UV protection is a fundamental requirement for preserving potency.
Without a Cap
The cap-free version allows you to choose exactly the closure you need: a pipette cap for essential oils, a fine mist spray for facial water, or a dropper for serums. The standard thread size of the 30ml Boston bottle ensures compatibility with most cosmetic closures.
