Common questions
What material is the 100ml bottle made from, and is it safe for serum?+
It is made from PET (polyethylene terephthalate), BPA-free and produced under ISO 9001, BSCI, SGS. PET is widely used for cosmetics, personal care, and daily-chemical formulas, and the bottle passes our standard compatibility and drop tests before shipment.
Which closure fits the 100ml PET disc-top bottle?+
The bottle ships with a disc-top cap for controlled, one-hand dispensing. Its 20 mm neck matches standard 20 mm closures, so we can also fit alternative caps — disc-top, flip-top, lotion pump, mist sprayer, or dropper — on request. Closure printing and color matching are available.
Can this PET bottle be made as a private mold or with custom embossing?+
Yes. We run in-house molding and blow-molding, so private molds, custom embossing, and exclusive shapes are available. Share your drawing or sample and we will engineer the tooling and provide pre-production samples within 7 days.
