Calaso Smooth 18-400 Serum Pump 0.1cc

What this packaging is

A 0.1cc dose-controlled output sets this pump apart for serums and lightweight formulas where precision matters. The Smooth 18-400 Serum Pump from Calaso features an 18/400 thread neck, making it compatible with a wide range of standard bottles across skincare and personal care lines. Built from PP with a glossy collar and smooth rounded actuator, it delivers a clean, minimal aesthetic that reads premium on shelf. European manufacturing brings design-forward thinking and tight quality tolerances you can count on. With accessible minimums for emerging brands or limited-edition runs, it's a smart fit for eye serums, face cleansers, body oils, and more.

Why brands choose this

• Precision dosing that protects high-value formulas: A 0.1cc output per stroke makes this pump especially well-suited for eye serums, facial oils, and concentrated actives — categories where over-dispensing is a real consumer frustration and a cost concern for brands. Controlled delivery also supports the growing trend toward intentional, waste-reducing skincare routines.
• 18/400 thread opens up your bottle options: The standardized 18/400 neck finish means this pump pairs with a wide inventory of existing bottles without custom tooling, cutting down development time and simplifying component sourcing — a real advantage for brand teams managing multiple SKUs or testing new formats.
• MOQ built for emerging brands and test launches: At 1,250 units minimum, this made-to-order pump is genuinely accessible for indie brands, limited-edition capsule collections, or new formula pilots — letting you validate a product line without the inventory risk that comes with high-volume commits.
