CLC 24-410 Smooth PP Treatment Pump with Overcap, 0.25cc Dosage with External Spring Design

What this packaging is

Precision meets protection in this 24-410 Smooth PP Treatment Pump with Overcap — a polypropylene pump engineered with an external spring design that keeps the spring in a dry chamber, completely isolated from the formula. That's a meaningful distinction for reactive serums and emulsions prone to ingredient-spring interaction and contamination risk. Delivering a consistent 0.25cc dose per stroke, it fits a 24-410 neck finish across a wide range of bottle formats. A multi-layer leak prevention design adds an extra layer of confidence during transit and storage. Available with heat stamping and aluminum shell finishes, this pump is built for face serum and moisturizer brands that want clinical precision and shelf-ready aesthetics in one component.

Why brands choose this

• Spring-isolated engineering protects formula integrity: The external spring sits in a dry chamber outside the liquid flow path — no formula contact, no corrosion risk, no contamination. This matters most for active-heavy serums and vitamin C or AHA moisturizers where metal-formula interaction is a real formulation concern.
• Consistent 0.25cc dosing builds consumer trust: Precise dose control per stroke means consumers get a repeatable application experience every time — no over-dispensing, no waste. In a serum category where a single bottle can retail above $80, dose accuracy directly reinforces perceived product value and encourages confident daily use.
• Multi-layer leak prevention designed for real-world logistics: The multi-layer leak prevention system protects against in-transit and in-storage leakage — a practical necessity for brands shipping DTC or through retail distribution channels where damaged packaging means returned product and brand equity hits.
