ZJ Pack 20-410 PP Slim Serum Pump, 0.23cc Dosage with External Spring & Long Overcap

What this packaging is

Precision-dosed at 0.23cc per stroke, the 20-410 PP Slim Serum Pump is engineered for high-performance dispensing of serums, foundations, primers, eye creams, and CC creams. Built from polypropylene with an external metal spring — meaning the spring never contacts the formula inside — this pump is a smart choice for brands working with sensitive or active-ingredient formulas. The 20mm 410 neck finish offers broad bottle compatibility, while the long overcap keeps the pump clean and travel-ready. A twist-lock function adds retail security, and decoration options including electroplating and water transfer printing give brands real shelf-impact flexibility.

Why brands choose this

• Spring never touches your formula: The external spring design is a genuine formulation win — it physically separates the metal component from the product, reducing contamination risk and making this pump compatible with a wider range of actives, acids, and sensitive skincare formulas without requiring full-plastic alternatives.
• Built for the serum and complexion category sweet spot: At 0.23cc per dose, this pump delivers the precise, controlled dispensing consumers expect from serums, foundations, and eye creams — formats where over-dispensing is a real friction point. The slim profile also reinforces the premium, clinical aesthetic that's driving growth across prestige skincare.
• Decoration versatility that supports brand differentiation: Electroplating and water transfer printing options mean brands aren't locked into a basic finish — the collar can be dialed up to match a luxury positioning or kept clean for a minimalist look, giving product developers meaningful customization without switching components mid-development.
