ZJ Pack 20-410 PP Slim Serum Pump, 0.23cc Dosage with External Spring, Clip Lock & Overcap

What this packaging is

Precision-dosed at 0.23cc per actuation, the 20-410 PP Slim Serum Pump is engineered for formulations where every drop counts. Built from polypropylene with an external metal spring that never contacts the product inside, it's a smart choice for active-rich serums, eye creams, face moisturizers, and foundations where formula integrity matters. The clip lock and overcap protect against travel spills and accidental dispensing, while the glossy collar and slim round profile keep the aesthetic clean and premium. A 20-410 neck finish means broad bottle compatibility, and decoration options including electroplating and spray coating give brands real room to customize.

Why brands choose this

• Formula integrity built into the hardware: The external spring mechanism sits outside the pump body entirely, meaning zero metal-to-formula contact. That's a meaningful spec for brands working with vitamin C serums, retinoids, or other oxidation-sensitive actives where even trace contamination can compromise stability.
• Clip lock and overcap earn their place in prestige skincare: Today's skincare consumer expects packaging that performs beyond the bathroom shelf — gym bags, travel kits, and carry-ons are part of the ritual. The combined clip lock and overcap prevent accidental dispensing and protect the pump tip, reducing waste and reinforcing a premium unboxing experience.
• Decoration versatility supports brand differentiation at shelf: Electroplating, spray coating, and water transfer printing give product developers genuine options to match the pump collar to a brand's visual identity — whether that's a mirrored metallic finish for a prestige serum or a matte tonal look for a minimalist skincare line. That flexibility is rare in a standard 20-410 component.
