ZJ Pack 24-410 PP Slim Serum Pump, 0.48cc Dosage with External Spring, Clip Lock & Clear Flush Overcap

What this packaging is

An external spring that never touches the formula — that's the standout feature of the 24-410 PP Slim Serum Pump. Built from durable polypropylene with a 0.48cc dose output, this slim pump delivers precise, controlled dispensing across face serums, moisturizers, cleansers, and hair treatments. The external spring design protects formula integrity by eliminating metal-to-liquid contact, making it particularly relevant for sensitive or active-ingredient formulations. A clip lock and clear flush overcap keep the product secure during transit and on-shelf. The glossy collar finish and decoration compatibility — electroplating, spray coating, water transfer printing — give brands real flexibility to make it their own. Manufactured in China, the 24-410 neck finish ensures broad bottle compatibility for streamlined development.

Why brands choose this

• Formula-safe dispensing via external spring design: The spring sits outside the pump body entirely, meaning it never contacts the product inside. For serums and actives where ingredient stability matters, this is a meaningful functional advantage — not just a spec detail.
• Precise 0.48cc dosage built for face and scalp rituals: Controlled, repeatable dosing is exactly what consumers expect from a serum or treatment pump. At 0.48cc per stroke, this pump aligns with category norms for facial serums and hair treatments, reducing waste and reinforcing the premium, clinical feel those categories demand.
• Broad decoration compatibility unlocks strong brand expression: Electroplating, spray coating, and water transfer printing are all on the table, giving product developers real latitude to match the pump collar to a full packaging system — whether that's a metallics-forward skincare line or a clean, matte aesthetic.
