This pack of 156 contains 15 ml amber glass dropper bottles with a solid aluminium screw cap. 15 ml is one of the most popular sizes in this category, and the aluminium cap is the most reliable choice for long-term storage: it provides an airtight closure and a chemically inert material.

Amber glass and UV protection
Amber glass blocks UV radiation and the shorter wavelengths of visible light, significantly slowing the oxidation of essential oils and botanical extracts. Light filtering combined with airtight aluminium closure provides a complete protective package: the contents are protected against both light and air.
Aluminium cap — details
The aluminium cap is chemically inert: it does not react with essential oils, does not allow odours to permeate, and contains no BPA, phthalates or other migratable substances. With many plastic caps, strong monoterpene-rich oils (citrus, conifer) can over time soften or crack the closure — this does not happen with aluminium. The cap is also easily recyclable, which is important to natural cosmetics makers.
Areas of use
- Long-term storage of essential oils and blends
- Bottling of natural serums and skin oils
- Filling tinctures and hydrosols
- Custom perfume bases
- Own-brand cosmetics with long shelf life
Cleaning and reuse
Before filling, wash the bottles in warm soapy water, rinse and dry. Do not soak the aluminium cap for extended periods — this preserves the flexibility of the sealing liner. Avoid the dishwasher to protect labels. Both glass and aluminium are fully recyclable materials.
