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

What this packaging is

Precision-dosed at 0.23cc per stroke, the 18-410 PP Slim Serum Pump delivers controlled, consistent dispensing for serums, foundations, primers, eye creams, and CC creams. Its standout feature: an external spring design that keeps metal completely out of contact with the formula — a real plus for sensitive actives or clean beauty formulations. The slim round profile fits the 18-410 neck finish standard across a wide range of bottles, giving brands genuine flexibility in bottle pairing. Decoration options including electroplating, spray coating, and water transfer printing make it easy to match any brand aesthetic. Built for prestige and clinical skincare packaging alike.

Why brands choose this

• Formula integrity protected by external spring design: The spring sits outside the pump body entirely, so it never touches your product. For serums, eye creams, or any formula with sensitive actives, this eliminates metal-contamination risk and opens the door to clean beauty and clinical positioning without reformulation compromises.
• Controlled 0.23cc dosage matches prestige skincare category expectations: Consumers expect precise, waste-free dispensing from serums and eye creams — and brands increasingly use dose control as a value-communication tool. At 0.23cc per stroke, this pump delivers the right amount every time, reinforcing product efficacy and extending perceived value.
• Decoration versatility supports premium and on-trend finishes: Electroplating, spray coating, and water transfer printing give brand teams real range — from high-gloss metallic looks to soft matte finishes — without needing a custom component. That flexibility compresses development timelines and keeps sampling straightforward across multiple SKUs.
