20-410 PP Slim Serum Pump with Clear Overcap, 0.23cc Dosage with External Spring

What this packaging is

Precision-dosed at 0.23cc per actuation, the 20-410 PP Slim Serum Pump with Clear Overcap is built around one standout detail: an external metal spring that stays completely isolated from the formula inside. That matters most for actives-heavy serums, eye creams, and foundations where metal contamination is a real formulation concern. Made from durable polypropylene with a glossy collar finish and transparent ABS overcap, it fits standard 20mm 410-neck containers — giving you broad compatibility across your existing lineup. Decoration-ready for electroplating, spray coating, and water transfer printing, this pump helps skincare and complexion brands present a finished, elevated look at shelf.

Why brands choose this

• Formula-safe external spring design: The metal spring sits entirely outside the pump body, never contacting the product inside — a meaningful advantage for serums and eye creams formulated with sensitive actives, peptides, or low-pH ingredients where metal exposure can compromise stability.
• Dose control built for high-trust skincare categories: A precise 0.23cc output per press helps brands signal efficacy and value to consumers — especially relevant in the serum and eye cream segments, where over-dispensing is a common friction point and portion control reinforces a premium positioning.
• Broad container compatibility with decoration versatility: The standard 20-410 neck finish works across a wide range of bottles and jars already in development or production, while support for electroplating, spray coating, and water transfer printing means the pump can be finished to match everything from minimalist clinical brands to richly decorated prestige lines.
