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

What this packaging is

Precision at 0.23cc per stroke — the 20-410 PP Slim Serum Pump is engineered for skincare formulas that demand controlled, mess-free dispensing. Its standout feature is an external spring mechanism that stays completely outside the pump body, meaning it never contacts the formula inside — a real advantage for preserving the integrity of serums, foundations, primers, eye creams, and CC creams. Built from polypropylene with a twist-lock function and slim actuator profile, it pairs cleanly with a wide range of 20-410 neck containers. Decoration options including electroplating, spray coating, and water transfer printing give brands room to customize this component into something distinctly their own.

Why brands choose this

• Formula-safe external spring design: The spring sits entirely outside the pump body and never touches the product inside — a key integrity advantage for active-rich serums, vitamin C formulas, and other oxidation-sensitive skincare that brands are increasingly launching in response to demand for high-performance ingredients.
• Precise 0.23cc dosage built for face-application formats: Micro-dosing is a growing expectation in prestige skincare, and a 0.23cc stroke delivers the controlled, single-pump portion consumers expect from serums, eye creams, and primers — reducing waste and reinforcing the perception of a clinical, efficacious product.
• Decoration versatility for brand-forward customization: Electroplating, spray coating, and water transfer printing options mean this pump can move from functional component to a visual brand asset — matching metal-finish cap trends, matte skin-tone palettes, or bold graphic treatments without switching suppliers or components.
