20.5-415 Patented Metal-Free PP, PETG, & TPE Bulb Dropper with 0.3-0.6cc Dosage

What this packaging is

Metal-free construction sets this bulb dropper apart in a category where rubber and aluminum components can complicate recyclability and formula compatibility. The 20.5-415 Patented PP, PETG, and TPE Bulb Dropper from FS Korea delivers a 0.3–0.6cc dosage range with a smooth collar and precision pipette — purpose-built for face serums and hair oils that demand clean dispensing and ingredient integrity. The all-polymer build supports higher recycling stream compatibility, and PCR content can be incorporated for brands with material reduction commitments. Manufactured in South Korea with a standardized 415 neck finish, this dropper pairs seamlessly across a wide bottle range — giving emerging and established brands alike a premium, format-flexible dropper worth building a product line around.

Why brands choose this

• Metal-free build protects formulas and recyclability: Unlike conventional droppers with aluminum or rubber components, this all-polymer PP/PETG/TPE construction eliminates metal contact points — reducing reactivity risk for sensitive serum and oil formulas while keeping the component within a single recycling stream for cleaner end-of-life processing.
• Precision dosing that matches the serum ritual: The 0.3–0.6cc variable dosage range and bulb-draw mechanism align directly with how consumers expect a face serum or hair oil dropper to perform — controlled, mess-free, and repeatable. As clinical skincare and scalp-care routines grow, packaging that supports precise application builds consumer trust and reduces product waste.
• Standardized 415 neck finish, broad bottle compatibility: The 20.5-415 neck finish is widely compatible across glass and plastic bottle formats, giving brand and development teams real flexibility to test different bottle silhouettes — or extend the same dropper cap across a product range — without requalifying the closure each time.
