Calaso Smooth 24-410 Serum Pump 0.5cc

What this packaging is

A 0.5cc dose per stroke makes the Smooth 24-410 Serum Pump one of the more precise dispensing options for leave-on and rinse-off formulas alike. Made from polypropylene with a glossy, smooth collar finish, it fits the 24/410 neck — one of the most widely used specs in personal care — meaning it pairs cleanly with a broad range of bottle formats. Designed in Europe by Calaso, a specialist in premium glass and closure systems, it handles everything from lightweight eye serums to thicker body lotions and hand creams without skipping or dripping. An MOQ of just 30 units makes this genuinely accessible for emerging brands, limited-edition launches, or sampling runs — rare at this quality level.

Why brands choose this

• MOQ of 30 units: an unusually low entry point that opens the door for indie brands, small-batch launches, and test-market runs without committing to large inventory — rare for a component with this level of finish quality.
• Consistent 0.5cc dose across viscosities: precision-engineered to dispense accurately whether the formula is a watery eye serum or a dense body lotion, reducing waste and supporting the kind of controlled application that consumers increasingly expect from premium skincare and body care.
• 24/410 neck compatibility across eight-plus categories: one pump spec that works for eye cream, shampoo, hand soap, face cleanser, body oil, and more — giving product developers and brand teams ranging flexibility without sourcing a new closure for every SKU.
