ZJ Pack 18-410 PP Slim Serum & Treatment Pump, 0.23cc Dosage with External Spring & Overcap

What this packaging is

An external spring design that never touches the formula inside — that's the standout engineering behind the 18-410 PP Slim Serum & Treatment Pump. Built from polypropylene with a precise 0.23cc dose per stroke, this slim round pump is purpose-built for face serums, eye creams, foundations, and primers. The 18-410 neck finish ensures a secure fit across compatible bottles, and the included overcap guards against contamination between uses. A glossy black finish gives it immediate shelf polish, with electroplating, spray coating, and water transfer printing available for custom branding. Manufactured in China, it's a clean-dispensing workhorse for prestige skincare and complexion lines.

Why brands choose this

• External spring keeps metal out of the formula: The spring mechanism sits outside the pump body entirely, so the liquid inside never contacts metal — a meaningful purity advantage for sensitive serums, peptide treatments, and eye creams where ingredient integrity matters.
• 0.23cc dosage aligns with premium serum rituals: Precise, controlled dispensing reduces waste and reinforces the 'less is more' use ritual that consumers expect from high-efficacy facial treatments and lightweight foundation formulas — a subtle but effective brand quality signal.
• Decoration versatility supports brand customization: Compatible with electroplating, spray coating, and water transfer printing, this pump can match a wide range of brand aesthetics — from minimalist skincare to full-glam complexion lines — without requiring a second vendor for finishing.
