Calaso Smooth 18-400 Serum Pump 0.1cc

What this packaging is

Precision-dosed at 0.1cc per stroke, the Smooth 18-400 Serum Pump delivers controlled dispensing that's especially valuable for higher-cost formulas like eye creams, face cleansers, and serums — where every drop matters. Built from polypropylene with an 18/400 thread, the glossy smooth collar and slim rectangular nozzle give it a clean, elevated finish that works equally well on body lotion, hand soap, shampoo, and body wash packaging. Manufactured in Europe where closure engineering standards run high, and available at accessible minimums of 1,250 units — low enough for indie launches or limited-edition runs — this pump gives emerging and established brands alike a refined, functional finish for any 18/400 bottle.

Why brands choose this

• Micro-dosing that protects high-value formulas: At 0.1cc per pump stroke, this closure helps prevent over-dispensing of premium serums, eye creams, and face cleansers — reducing waste and reinforcing a sense of quality control that resonates with today's ingredient-conscious consumer.
• Accessible minimums built for flexible development: At just 1,250 units MOQ, brands can test packaging across multiple SKUs, launch limited editions, or move into a new category without overcommitting inventory — a real advantage in fast-moving personal care and beauty development cycles.
• One closure, eight end-use categories: From shampoo and body wash to hand cream and eye serum, the 18/400 thread and adaptable dip tube make this pump viable across a wide product range — simplifying component sourcing and giving brand teams more flexibility when building or extending a line.
