20mm Tamper Evident Dropper Cap

Fitted with an integral breakable security band. The ring will rupture visibly upon first opening, offering obvious evidence of tampering, deterring unauthorized opening and protecting product authenticity during sales and distribution.

Matched with internal sealing liner for tight closure after screwing on, curbing liquid volatilization and leakage. The supporting dropper enables quantitative liquid extraction, bringing convenient and controlled usage experience for essential oils and serums.

Customized for standard 20mm bottle necks, this cap fits most mainstream cosmetic and essential oil bottles smoothly. It combines anti-theft protection, sealing performance and dripping application into one integrated packaging solution.
