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

What this packaging is

Keeping the spring outside the pump body is a small engineering choice with a big formulation payoff — and it's the defining feature of this 24-410 PP Slim Serum & Treatment Pump. The external spring never contacts the liquid inside, making it a smart pick for sensitive or active-ingredient formulas in face moisturizers, serums, face cleansers, hand creams, and hair treatments. Delivering a precise 0.48cc dose per stroke, it fits standard 24mm / 410-neck containers and arrives with a clear recessed overcap for a clean, professional look. Decoration-ready via electroplating, spray coating, and water transfer printing — this pump gives emerging and established brands alike a polished, customizable dispensing format.

Why brands choose this

• Spring-outside design protects formula integrity: The external spring sits completely outside the pump body and never touches the product inside — a genuine advantage for formulas with active ingredients, naturals, or preservative-sensitive systems that can degrade on contact with metal components.
• Precision 0.48cc dosage supports category rituals consumers expect: Controlled, repeatable dosing is a standard expectation in the prestige skincare space, and this pump delivers it across a wide range of viscosities — from lightweight serums to richer hand creams — reducing waste and reinforcing a premium application experience.
• Decoration versatility opens real branding range: Compatible with electroplating, spray coating, and water transfer printing, this pump can read clinical and minimal or bold and editorial depending on finish — giving brand and product development teams flexibility across SKUs without switching components.
