ZJ Pack 24/410 PP Serum/Treatment Pump, 0.48cc Dosage, Twist Lock

What this packaging is

An external metal spring — positioned completely outside the pump body and never touching the formula — makes this pump a smart pick for sensitive, active-rich serums and hair treatments that can't afford compatibility risks. The 24/410 PP Serum/Treatment Pump delivers a precise 0.48cc dose per stroke with a twist-lock closure that prevents accidental dispensing in transit or on-counter. Built from polypropylene with a glossy collar finish, it fits the standard 24-410 neck found across most serum and treatment bottles. Available in custom colors with decoration options including electroplating, spray coating, and water transfer printing — giving brands real room to differentiate on shelf.

Why brands choose this

• External spring protects sensitive formulations: The metal spring sits fully outside the pump body, eliminating liquid contact — a critical design detail for brands formulating with acids, retinoids, peptides, or botanical actives where metal exposure can degrade efficacy or cause discoloration.
• Precision dosing supports premium positioning: A consistent 0.48cc output per stroke gives consumers a controlled, waste-free experience — directly aligned with the growing consumer expectation that premium serums and treatments feel measured and intentional, not gloopy or over-dispensed.
• Decoration versatility for shelf differentiation: Electroplating, spray coating, and water transfer printing options — plus custom color availability — let brand teams push beyond a standard pump aesthetic and build packaging that reads as a cohesive brand object, not just a functional cap.
