CLC 20-410 Ribbed PP Treatment Pump, 0.25cc Dosage with External Spring Design

What this packaging is

An external spring design sets this pump apart from standard treatment pumps — the spring sits in a dry chamber, completely outside the liquid flow path, eliminating contact with your formula and removing corrosion and contamination risk from the equation. The 20-410 Ribbed PP Treatment Pump delivers a precise 0.25cc dose per actuation, making it a natural fit for face serums, eye creams, spot treatments, and moisturizers where dosage control matters. Built from PP with a multi-layer construction that actively prevents leaks, it pairs with the wide range of containers carrying a 20mm neck and 410 finish. Hot stamp and aluminum shell options let you dial in the aesthetic to match your brand positioning.

Why brands choose this

• Formula-isolated spring design: a spring that never contacts your formula isn't a small detail — it's a meaningful engineering decision. The external spring chamber prevents corrosion from reactive actives like acids and retinoids, protecting both formula integrity and pump longevity across the full product lifecycle.
• Precision 0.25cc dosing for high-performance skincare: consistent low-volume dosing is the standard expectation for serums and eye creams, where over-dispensing wastes expensive actives and under-dispensing frustrates consumers. The fixed 0.25cc output removes guesswork and aligns with the careful, ritual-driven application that prestige skincare consumers expect.
• Decoration flexibility that supports brand differentiation: compatibility with hot stamping and an optional aluminum shell means this pump can read as understated and clinical or as premium and retail-ready — without changing the core component. That range makes it a practical choice for brand teams developing across multiple price points or retail channels.
