18-DIN Bulb Dropper

What this packaging is

Bent ball tip precision and a child-resistant, ribbed collar make the 18-DIN Bulb Dropper a standout closure for face serums and hair oils that demand controlled, mess-free dispensing. Made from quality PP with a matte-finished grip collar and DIN18 thread, this Calaso dropper integrates cleanly with a wide range of glass and plastic bottles. Designed and sourced in Europe, it carries the kind of considered engineering that brands notice — and consumers feel. With an MOQ of just 1 unit, it's genuinely accessible for indie launches, sampling, or limited-edition development. A refined dropper that makes the application ritual feel as premium as the formula inside.

Why brands choose this

• MOQ of 1 unit — no minimums, no risk: An MOQ starting at a single unit is almost unheard of in primary packaging. It removes the usual barrier to entry for emerging brands, formula testing, or short-run launches — you can validate packaging fit before committing to volume.
• Bent ball tip design supports consumer adoption of dropper formats: As dropper applicators grow across the serum and scalp oil categories, ease of use is a real retention driver. The bent ball tip on this dropper makes targeted application — along the hairline, around the eye area — intuitive enough that consumers actually use it correctly, which means they see better results and come back.
• DIN18 thread opens up broad closure compatibility: Standardized DIN threading means this dropper works across a wide range of bottle necks without custom tooling, giving brand and development teams flexibility to iterate on the bottle while keeping the dropper constant — a practical advantage during packaging development cycles.
