ZJ Pack 24/400 PP Serum/Treatment Pump, 0.48cc Dosage, Twist Lock

What this packaging is

An external metal spring that never touches your formula — that's the standout detail on the 24/400 PP Serum/Treatment Pump. Built for facial care, this polypropylene pump delivers a precise 0.48cc dose per stroke, giving brands and consumers consistent, controlled dispensing for serums, moisturizers, and cleansers. The 24-400 neck finish pairs with a twist lock mechanism that doubles down on leak prevention — critical for retail-ready packaging and travel use. A glossy collar finish and decoration compatibility (electroplating, spray coating, water transfer printing) make it easy to build a premium brand aesthetic around a workhorse component.

Why brands choose this

• External spring protects sensitive formulas: The spring sits completely outside the pump body, eliminating metal-to-formula contact — a genuine advantage for active-forward serums, acid treatments, and clean beauty products where ingredient compatibility is non-negotiable.
• Twist lock and clip lock for retail and travel confidence: Dual security features prevent accidental dispensing in transit or on shelf — a strong selling point as brands respond to growing consumer demand for leak-proof, travel-ready skincare packaging.
• Finish versatility unlocks premium branding at scale: Compatibility with electroplating, spray coating, and water transfer printing means this pump can be customized to match a broad range of brand aesthetics — from clinical minimalism to luxury skincare — without sourcing a secondary component.
