The 15 ml cobalt blue glass bottle with a black pipette dropper is a classic, refined format for home-made cosmetics and essential oil recipes: the light filtering of the cobalt blue glass protects delicate scent profiles, while the pipette dropper allows precise drop-by-drop dispensing. This pack of 156 is designed for those who regularly create their own compositions and need accurate dosing.

Nominal fill capacity 15 ml, bottle height approximately 65 mm, diameter 28 mm, empty weight 30-35 g each. Total package weight is around 5.15 kg. Country of origin: China.
Cobalt blue glass — UV protection and vintage aesthetics
Cobalt blue glass blocks UV radiation and shorter wavelengths of visible light, which is particularly favourable for storing delicate linalool-based essential oils (lavender, bergamot, ylang, neroli, jasmine). The deep blue tone also lends a characterful vintage apothecary feel to finished preparations. Blue glass is not fully opaque; under appropriate lighting, contents may be faintly visible, which makes fill-level checking easier.
Pipette dropper — precise drop-by-drop dosing
The black pipette dropper consists of a glass stem and a black rubber bulb. A gentle squeeze of the bulb draws up the right amount of liquid, then releases it drop by drop — ideal for any preparation requiring exact ratios or dilutions. On the 15 ml bottle, the pipette stem is longer than on the 10 ml version, making the bottom of the bottle easier to reach. An average pipette draw lifts about 0.7-1 ml, corresponding to 18-30 drops depending on oil viscosity. The rubber bulb is made from BPA-free material, but for long-term storage — especially with citrus essential oils — it is advisable to switch to an aluminium cap.

Cleaning and storage
We recommend rinsing new bottles in warm soapy water before first use. Disassemble the pipette separately for cleaning: separate the rubber bulb from the glass stem, wash both, and dry completely before reassembly. An isopropyl alcohol rinse is the most effective way to remove residual scents. Store filled bottles in a cool, dark place.
