ZJ Pack 24-410 Patented Variable Dispensing PP Slim Serum & Treatment Pump with External Spring & Adjustable Dosage (0.35cc - 0.48cc)

What this packaging is

An external spring that never touches the formula — that's the engineering detail that sets this PP slim serum pump apart. The 24-410 Patented Variable Dispensing Pump lets users dial between 0.35cc and 0.48cc output by simply rotating the pump head, giving brands and consumers real dose control in one component. That external spring design also makes it genuinely compatible with oil-based serums and treatments — a formulation type that trips up standard pumps. Fits a 24-410 neck finish, works across face serums, moisturizers, hair treatments, and cleansers, and supports electroplating, spray coating, and water transfer printing for strong on-shelf branding.

Why brands choose this

• Patented adjustable dosage — a real consumer differentiator: The twist-to-adjust output (0.35cc or 0.48cc) is a patented feature that puts dose control in the consumer's hands — aligning with the growing skincare trend around intentional, waste-free application. It's a tangible, storytellable feature that can anchor your product positioning.
• Oil-formulation ready without reformulating around the packaging: The external spring sits completely outside the liquid path, making this pump compatible with oil-based serums and treatments — categories growing fast in prestige skincare. Brands developing facial oils, hair treatment oils, or hybrid serum-oils won't need to compromise on format.
• Decoration versatility supports premium and mass-market positioning alike: Electroplating, spray coating, and water transfer printing options mean this pump can move from a clean, minimalist serum aesthetic to a high-gloss premium finish without changing the component. One tooled component, multiple brand expressions across a full skincare or haircare range.
