ZJ Pack 24-410 PP Serum & Treatment Pump, 0.48cc Dosage with External Spring, Wide Collar & Clear Recessed Overcap

What this packaging is

An external spring that never touches your formula — that's the standout detail on this 24-410 PP Serum & Treatment Pump. The spring sits outside the pump body entirely, keeping it away from sensitive actives, oils, or water-based treatments that could degrade metal over time. Built from polypropylene with a PE gasket and dip tube, it delivers a consistent 0.48cc dose per press — precise enough for serums and treatments where overuse is a real concern. The clear recessed overcap and wide collar give it a clean, retail-ready look, and the 24-410 neck finish works across a broad range of bottle formats. Electroplating and spray coating options open the door for custom branding. A smart pick for face moisturizers, cleansers, hand creams, and hair treatments where formula integrity and dose accuracy matter.

Why brands choose this

• Formula-safe external spring design: The spring mechanism sits entirely outside the pump body, eliminating metal-to-formula contact. This is a meaningful protection layer for brands working with actives, acids, or oil-rich formulations that can corrode conventional internal springs and compromise product integrity over time.
• Consistent 0.48cc dosing for efficacy-forward positioning: Precise, repeatable dosing isn't just a functional win — it's a brand story. In a market where consumers are increasingly skeptical about overuse and waste, a pump that delivers exactly the same amount every press supports both efficacy claims and a more intentional product experience.
• Multi-category versatility across four distinct end uses: Face moisturizers, cleansers, hand creams, and hair treatments all fit this pump's profile — making it a strong candidate for brand teams developing a cohesive line across categories. One qualified component across multiple SKUs simplifies supplier relationships and speeds up the ranging process.
