This 192-piece pack contains 10 ml cobalt blue glass dropper bottles fitted with aluminium screw caps. The set is intended for crafters, essential oil blenders, small-batch cosmetic makers and herbalists who need a consistent, light-protective container for sensitive liquids.
Why use cobalt blue glass?
Cobalt blue glass blocks roughly 99% of visible light and a significant portion of UV radiation. This noticeably slows the oxidation of essential oils, cold-pressed carrier oils, tinctures and active-ingredient serums, helping to preserve aroma intensity and extend shelf life compared to clear or amber glass.

Aluminium cap and dropper insert
The aluminium cap does not rust and remains stable in contact with acidic or oil-based contents, unlike some lower-grade metal alloys. The screw-on dropper insert allows controlled dispensing: drop-by-drop application for thicker oils and a thin pouring stream for lighter liquids.
Compatibility with other accessories
The GPI/DIN 18 mm neck is a standard finish, so most pipette inserts, fine-mist sprayers and roll-on balls listed in our shop will fit these bottles, as long as the accessory's product page specifies the same thread size. This makes the 192-bottle pack usable across several product lines.
