Drop-by-drop precise dosing is not a luxury but a practical necessity when working with concentrated natural cosmetics and essential oil blends. This 88-piece pack contains 50 ml black glass bottles with black pipette droppers — combining full light blocking with precise dispensing for small businesses and DIY makers who value the user experience.
What is in the pack of 88
88 black glass bottles of 50 ml + 88 black pipette droppers (glass pipette plus black rubber bulb). Height: ~100 mm, diameter: ~42 mm, empty weight: ~75 g per piece. Pack gross weight is approximately 7.26 kg. The pipette screws into the GL18 neck thread and can draw approximately 4 ml of liquid at a time. Country of origin: China.
Black glass and full light blocking
Opaque black glass blocks essentially the entire light spectrum, including the UV range and almost all wavelengths of visible light. This is particularly important for light-sensitive contents: citrus essential oils, cold-pressed botanical oils (argan, jojoba), and facial serums containing vitamin C or retinol. Black glass is the most effective way to preserve scent profile and active ingredient content over the long term.
Pipette dropper details
The pipette consists of a glass tube and a black silicone (or rubber) bulb. Squeezing the bulb draws liquid into the pipette, then releasing it dispenses the liquid drop by drop. This design enables precise dosing without having to tilt the entire bottle. An average 50 ml essential oil blend contains approximately 1000-1500 drops, so the pipette serves as a dispensing tool for an extended period. The rubber component may eventually deteriorate from strong essential oil exposure — replacement pipettes are readily available.
Areas of use

Cleaning and maintenance
Before filling, rinse the pipette with warm water and a little washing-up liquid, then rinse thoroughly with clean water. To remove residual scent, 70% isopropyl alcohol can be used. Handle the rubber bulb gently: do not fully compress it, and avoid prolonged high temperatures. The glass part of the pipette and the bottle can be washed in the dishwasher, but the rubber bulb is best cleaned by hand.
