Calaso 18-400 Bulb Dropper

What this packaging is

Precision dispensing in a clean, minimal form — the Calaso 18-400 Bulb Dropper is a polypropylene dropper closure built for face serums and hair oils where dose control matters. The 18/400 thread pairs reliably with compatible glass bottles, while the straight ball-tip pipette delivers controlled, drop-by-drop application that consumers actually notice. A glossy smooth collar and cylindrical black cap give it a professional finish that works across aesthetic directions. European manufacturing brings design craft and quality consistency to the component. With accessible minimums of just 1,000 units, it's a smart entry point for emerging brands or limited-edition formulations looking for a polished, functional dropper.

Why brands choose this

• Dose-control that matches the serum ritual: The straight ball-shaped tip delivers precise, drop-by-drop dispensing — a format consumers already associate with face serums and hair oils, reinforcing application confidence and reducing waste at point of use.
• 1,000-unit minimums for lean launches: At just 1,000 units MOQ, this dropper is genuinely accessible for indie brands, test runs, or limited-edition drops without locking up capital in deep inventory commitments.
• European-made quality on a matched closure system: Manufactured in Europe with expertise from specialist closure partners, the 18/400 thread fit is engineered to perform with compatible bottles — reducing leakage risk and simplifying vendor sourcing.
