Made of stable high borosilicate glass, this cylindrical bottle will not react with stored liquids. Amber glass blocks UV rays to shield light-sensitive oral liquids, plant extracts and serums from spoilage, while clear glass showcases liquid texture for retail display. The crimp neck pairs with rubber stoppers and tear aluminum caps for full airtight sealing, stopping leakage, oxidation and ingredient volatilization during shipping and storage. Its smooth flat body offers ample space for logos and labels.It works perfectly for oral liquids, skincare serums, essential oils, plant extracts and test samples, suitable for health brands, cosmetic factories and labs.
