Calaso 18-DIN Monomaterial Dropper Cap

What this packaging is

Precision dispensing starts with the right cap — and the 18-DIN Monomaterial Dropper Cap delivers exactly that. Engineered in PP with a DIN18 threaded closure, this white ribbed cap pairs seamlessly with standard glass dropper bottles for tinctures, face serums, and hair oils. The monomaterial PP construction keeps the component stream clean and consistent, while the minimalist cylindrical silhouette reads as polished and professional at shelf. Sourced from Calaso's manufacturing base in the Netherlands, it carries the precision engineering heritage you'd expect from European closures. With accessible minimums for emerging brands or limited-edition runs, it's a smart starting point for any dropper-format launch.

Why brands choose this

• Monomaterial PP simplifies your component sourcing: A single-material PP construction means consistent quality across the cap, no multi-material compatibility issues to troubleshoot, and a cleaner story for brand teams tracking material consistency across their packaging lineup.
• DIN18 threading locks into dropper bottle compatibility: The standardized DIN18 neck finish means this cap fits a wide range of glass dropper bottles without custom tooling — reducing development time and giving brands more flexibility when sourcing bottles across multiple suppliers.
• Accessible MOQ opens the door for small-batch tincture launches: With a minimum order of just 50 units, this cap is genuinely workable for emerging wellness and botanical brands testing a tincture SKU, running a limited-edition drop, or validating a formula before committing to a full production run.
