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

What this packaging is

Precise 0.48cc dosage control meets formula-safe engineering in the 24/410 PP Serum/Treatment Pump — a twist-lock pump built for serums, moisturizers, hand creams, and hair treatments where clean dispensing matters. The standout feature is its external metal spring, positioned outside the pump body entirely, so it never contacts the formula. That design choice is meaningful for reactive actives, botanical extracts, or anything sensitive to metal exposure. Crafted from durable polypropylene with a glossy collar finish, it fits standard 24mm/410-neck containers and accepts electroplating, spray coating, and water transfer printing for custom aesthetics. A smart, formula-conscious pump for brands that don't want to compromise on chemistry or shelf presence.

Why brands choose this

• Formula-safe external spring design: The metal spring sits completely outside the pump body, eliminating contact with your product. This is a genuine functional advantage for brands formulating with reactive botanicals, acids, or metal-sensitive actives — protecting formula integrity from pump to skin.
• Precision dose control built for treatment formats: A fixed 0.48cc output per stroke means consistent dispensing every time, which matters for high-potency serums and treatments where over-dispensing wastes expensive actives. Brands can also use this as a consumer confidence signal — the pump does the metering for them.
• Decoration flexibility supports brand differentiation at shelf: Electroplating, spray coating, and water transfer printing open up a wide range of finishes — from sleek metallics to matte or patterned looks — letting brand teams create a distinct shelf presence without a custom-tooled component. The glossy collar adds an elevated baseline even undecorated.
