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

What this packaging is

An external spring that never touches the formula — that's the standout engineering behind the 20-410 PP Slim Serum & Treatment Pump. By positioning the spring outside the pump body, this 0.23cc dosage pump protects sensitive formulations like face serums, eye creams, foundations, primers, and BB creams from metal contact and potential contamination. Built in PP with a glossy collar and slim actuator profile, the 20-410 neck finish makes it a natural fit for standard treatment and serum bottles. Decoration options including electroplating, spray coating, and water transfer printing let brands dial in the right aesthetic for any positioning.

Why brands choose this

• External spring protects formula integrity: The spring sits entirely outside the pump body, meaning zero metal-to-liquid contact. For oxidation-sensitive actives in serums, eye creams, and foundations, this is a meaningful formulation safeguard that reduces stability risk without adding complexity.
• Precision 0.23cc dosage supports consumer confidence: Consistent micro-dosing is increasingly expected in premium skincare, where over-dispensing erodes trust and product value. A controlled output per press aligns with how consumers are being educated to apply serums and treatments — a small but brand-relevant detail at point of use.
• Decoration versatility enables brand differentiation: Electroplating, spray coating, and water transfer printing are all on the table, so this pump can read as clinical, minimalist, or luxe depending on finish choice. For brand teams developing across multiple price tiers or seasonal collections, that flexibility reduces SKU complexity.
