ZJ Pack 24-410 PP 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 detail that makes a real difference for sensitive formulations — and that's exactly what this 24-410 PP Serum & Treatment Pump delivers. The external spring mechanism never contacts the liquid inside, making it a smart pick for face moisturizers, face cleansers, hand creams, and hair treatments where formula integrity matters. Built from polypropylene with a PE gasket and dip tube, it delivers a precise 0.48cc dose per actuation. The clear recessed overcap keeps things clean and travel-ready. A reliable, no-fuss dispensing component for brands that take formulation quality seriously.

Why brands choose this

• Formula-safe external spring mechanism: The spring sits entirely outside the liquid pathway — a genuine advantage for brands working with active-rich serums, sensitive skincare, or preservative-free formulations where metal or spring contact could compromise stability or efficacy.
• Precision 0.48cc dosage for premium positioning: Controlled dose-per-actuation is increasingly expected in treatment-positioned products. A consistent 0.48cc output reduces product waste, supports efficacy claims, and reinforces the clinical credibility that today's skincare consumers look for in serums and targeted treatments.
• Broad category fit with a single component: One pump format that works across face moisturizers, cleansers, hand creams, and hair treatments gives product development and ranging teams a reliable go-to component that simplifies supplier management and speeds up new SKU development across different categories.
