ZJ Pack 20-410 PP Serum & Treatment Pump, 0.23cc Dosage with External Spring & Domed Clear Overcap

What this packaging is

An external spring that never touches your formula — that's the standout detail on this 20-410 PP Serum & Treatment Pump. Designed for formulation compatibility, the external spring mechanism keeps hardware completely separated from liquid, making it a smart pick for sensitive actives, water-based serums, and oil-heavy treatments alike. The 0.23cc dosage delivers consistent, controlled dispensing across face serums, foundations, primers, eye creams, and BB creams. Built from polypropylene with a domed clear overcap and decoration options including electroplating and spray coating, this pump gives multi-SKU brand teams a reliable, customizable workhorse across a full skincare lineup.

Why brands choose this

• Formulation-safe external spring design: The spring sits completely outside the pump body, eliminating metal-to-formula contact — a critical advantage for brands working with vitamin C, retinoids, acids, or any oxidation-sensitive active where ingredient integrity directly affects efficacy claims.
• Precise 0.23cc dosage built for high-value skincare: Consistent low-volume dispensing reduces waste and supports a premium consumer experience — especially relevant as brands in the serum and treatment space face pressure to justify per-ml cost with every application ritual.
• Decoration-ready for brand differentiation: Compatible with electroplating, spray coating, and water transfer printing, this pump can be finished to match a wide range of brand aesthetics — from clinical minimalism to luxury metallic — without sourcing a separate decorated component.
