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

What this packaging is

An external spring design that never contacts the formula — that's the standout feature of this 20-410 PP Slant-Top Serum & Treatment Pump. Built for precision dispensing at 0.23cc per dose, it's a strong fit for face serums, foundations, primers, eye creams, and BB creams. The spring sits outside the pump body entirely, making it broadly compatible with active-heavy, oil-based, or sensitive formulations that can degrade metal components. The PP construction with domed clear overcap delivers a clean, finished look right out of the box. Decoration options including electroplating, spray coating, and water transfer printing give brand teams real customization flexibility.

Why brands choose this

• External spring keeps metal out of your formula: The spring is positioned entirely outside the pump body, eliminating metal-to-formula contact. This makes it a reliable choice for vitamin C serums, retinol treatments, and other actives that are sensitive to metal exposure — no reformulation workarounds needed.
• 0.23cc dosage supports precision application across multiple categories: The controlled dose output is well-matched to high-value serums, eye creams, and primers where over-dispensing is a real consumer pain point. Consistent dosing also helps brands align with per-use cost messaging and supports product efficacy claims tied to application amount.
• Decoration versatility supports brand differentiation at scale: Electroplating, spray coating, and water transfer printing are all compatible options, giving product developers meaningful flexibility to match brand aesthetics — from minimalist skincare to full-coverage foundation lines — without sourcing a separate decorated component.
