1oz / 30ml Refillable PET Square Double-Wall Airless Pump Bottle with Overcap & PP Inner Bottle, 0.23cc Dosage

What this packaging is

A square double-wall silhouette and a precision 0.23cc airless pump make this 30ml refillable bottle a standout choice for high-performance skincare. The 1oz / 30ml Refillable PET Square Double-Wall Airless Pump Bottle pairs a PP inner bottle with a protective overcap, keeping formulas fully isolated from air exposure until dispensing. That airless mechanism handles high-viscosity textures well, making it a natural fit for face serums, moisturizers, eye serums, foundation, and primer. The refillable design supports a genuine sustainability story, reducing single-use packaging waste. Compact at 125mm tall, it's built for both retail shelf presence and on-the-go use.

Why brands choose this

• Airless dosing protects high-value formulas: The 0.23cc pump delivers consistent, controlled output while the double-wall construction and PP inner bottle eliminate air contact entirely — critical for oxidation-sensitive serums, eye treatments, and foundation where formula integrity directly affects consumer results.
• Square silhouette creates ownable shelf presence: The flat-sided, upright profile stands apart from the round airless bottles that dominate skincare shelves, giving brands a distinctive visual anchor across serum, moisturizer, and complexion lines without requiring custom tooling.
• Refillable design opens a real sustainability story: Built for refill from the start, this bottle supports packaging waste reduction goals and gives brand teams a credible, tangible sustainability claim — increasingly expected by consumers in premium skincare and makeup categories.
