ZJ Pack 18-410 PP Slim Serum Pump, 0.23cc Dosage with External Spring & Long Overcap

What this packaging is

An external spring that never touches your formula — that's the standout engineering behind the 18-410 PP Slim Serum Pump with 0.23cc dosage and long overcap. Designed for precision dispensing of face serums, foundations, primers, eye creams, and CC creams, this polypropylene pump pairs a slim, round profile with the 18-410 neck finish for broad container compatibility. The 0.23cc dose keeps application controlled and waste minimal. Decoration-ready with electroplating, spray coating, and water transfer printing options, it gives brand teams real room to differentiate. Manufactured in China, it's a reliable, customizable pump built for prestige skincare and cosmetics lines that demand both performance and shelf presence.

Why brands choose this

• External spring protects formula integrity: The spring sits entirely outside the pump body, eliminating liquid contact and reducing contamination risk — a meaningful advantage for active-rich serums, eye creams, and emulsion-based foundations where ingredient stability is non-negotiable.
• Precision 0.23cc dose for high-value formulas: A measured, low-volume actuation minimizes product waste with every use — a clear consumer confidence signal for premium serums and eye creams where over-dispensing is a common friction point and consumers are paying attention to how far a product goes.
• Decoration versatility for brand-building at shelf: Electroplating, spray coating, and water transfer printing compatibility means this pump can be finished to match nearly any brand aesthetic — from minimalist matte to metallic luxe — without switching components across your foundation, primer, and serum range.
