The 100 ml format represents a step up from the personal 50 ml size: it is suitable for massage oil bases, DIY body lotion formulations, professional skincare bottling, and for finished products intended for sale or gifting that require a larger volume. This 70-piece pack contains 100 ml black glass bottles supplied without caps, so you can choose your own closure to match your application.
What is in the pack of 70
70 black glass dropper bottles, 100 ml each, supplied without caps. Height: ~130 mm, diameter: ~52 mm, empty weight: ~130 g per piece. Pack gross weight is approximately 10.01 kg. The bottles feature a standard GL18 neck thread, making them compatible with most black pipette droppers, aluminium caps, child-resistant closures, and screw caps available on the market. Country of origin: China.
Black glass and full light blocking in 100 ml
In the 100 ml format, light protection matters even more than for smaller volumes, because the contents remain in the bottle for a longer period (1-3 months of use). Opaque black glass blocks essentially the entire light spectrum, including the UV range and almost all wavelengths of visible light. This is particularly justified for massage oil bases (with many cold-pressed botanical oils), vitamin C serums, and essential-oil-containing body lotions.
Advantages of supplying without caps
The capless format offers flexibility: you can use the same bottles with different closures depending on your purpose. Aluminium cap for massage oil bases, black pipette dropper for concentrated facial oils, child-resistant cap for products intended for family households, or tamper-evident dropper cap for professional retail. Thanks to the GL18 neck standard, all Természetkosár BLDB-family caps and droppers will fit.

Cleaning and reuse
Before filling new bottles, wash them in warm water with washing-up liquid, rinse thoroughly, and let them dry completely. For previously used bottles, rinse with 70% isopropyl alcohol to remove residual scent. Avoid the dishwasher, as prolonged high temperatures and concentrated detergent can damage the glass. Black glass can be placed in standard glass recycling streams.
