18-DIN Bulb Dropper

What this packaging is

Ribbed grip, clear glass pipette, and a narrow precision tip — the 18-DIN Bulb Dropper by Calaso is built for controlled, drop-by-drop dispensing in face serums and hair oils. Made from white polypropylene with a DIN18 thread neck finish, it pairs cleanly with compatible glass bottles to create a cohesive, professional package. Sourced from Europe where closure engineering runs deep, this dropper reflects the kind of detail-oriented design that holds up under daily consumer use. Custom color matching is available, and with minimums starting at just 50 units, it's genuinely accessible for emerging brands testing new formulas or planning limited-edition launches.

Why brands choose this

• MOQ of 50 units — seriously accessible for early-stage brands: At just 50 units minimum, this dropper removes one of the biggest barriers for indie brands and formulators — you can validate packaging before committing to a full production run, which makes it a smart fit for pilot launches, sampling programs, or seasonal limited editions.
• Narrow-tip pipette designed for the serum and hair oil ritual: The clear glass pipette with a fine dispensing tip gives consumers the dose control they expect from a premium dropper format — it reinforces the careful, intentional application ritual that both face serum and hair oil users look for, which helps the packaging earn its place in a competitive category.
• European-made closure engineering with custom color availability: Calaso's DIN18 bulb dropper comes from a manufacturing tradition where fit and finish matter — the DIN18 thread ensures reliable compatibility with standard glass bottles, and custom color options mean brands aren't locked into white if the brief calls for something more on-brand.
