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

What this packaging is

An external metal spring that never touches your formula — that's the standout engineering behind the 20-410 PP Slim Serum & Treatment Pump. Designed for 20-410 neck finishes, this polypropylene pump delivers a precise 0.23cc dose per actuation, making it a strong fit for face serums, foundations, primers, eye creams, and BB creams where dosage control matters. The long clear overcap keeps the pump protected between uses, and a glossy collar finish gives it a clean, polished look on shelf. Manufactured in China, it supports decoration via electroplating, spray coating, and water transfer printing — giving brand teams real flexibility to match packaging to identity.

Why brands choose this

• Formula-safe external spring design: The spring sits outside the pump body entirely, never coming into contact with the product inside. This matters for sensitive formulations — serums, actives, eye creams — where metal exposure can affect stability, giving formulators and brand developers one less compatibility concern to manage.
• Controlled 0.23cc dosing for high-value formulations: Per-actuation precision is a real asset for premium serums and treatments where over-dispensing erodes margin and frustrates consumers. At 0.23cc, this pump delivers a metered dose that aligns with how consumers expect concentrated skincare products to perform — and supports the clinical, results-driven positioning many prestige brands are leaning into.
• Broad decoration compatibility for brand expression: Electroplating, spray coating, and water transfer printing options mean this pump can be finished to match a wide range of brand aesthetics — from clean minimalist to bold and editorial. For teams managing multiple SKUs across foundations, primers, and serums, that flexibility simplifies tooling decisions across a product range.
