ZJ Pack 20-410 Slim PP Serum Pump with 0.23cc Dosage & Clear Overcap

What this packaging is

Precision dosing in a slim profile — that's the defining feature of the 20-410 Slim PP Serum Pump with 0.23cc Dosage & Clear Overcap. Built from PP plastic with a 20-410 neck finish, this pump delivers a consistent 0.23cc dose per stroke, making it a reliable choice for face serums, eye creams, primers, foundations, and hair treatments. Its external metal spring sits outside the pump body entirely, keeping metal away from sensitive formulations and preserving product integrity. The clear overcap protects the actuator between uses. Decoration options — electroplating, spray coating, water transfer printing — give brands real room to differentiate on shelf.

Why brands choose this

• Formula-safe external spring design: The spring sits completely outside the pump body and never contacts the liquid inside — a meaningful engineering detail for brands working with active-heavy serums, pH-sensitive formulas, or any formulation where metal contact could compromise stability or efficacy.
• Consistent 0.23cc dosing builds consumer trust: Precise dose control means consumers get the same measured amount every pump, reducing waste and over-dispensing. As efficacy-first skincare continues to drive purchasing decisions, packaging that signals clinical precision — like a fixed-dose pump — reinforces the product story at point of use.
• Wide end-use versatility across prestige and mass categories: The slim actuator profile and 20-410 neck finish make this pump a strong fit across face serums, eye creams, primers, foundations, and hair treatments — giving multi-SKU brand teams and contract manufacturers a single component they can range across an entire product lineup without retooling.
