What sets this jar apart is its thoughtful fusion of material and design. Crafted via professional PET injection molding, the thick-walled structure (adjustable for your needs) ensures it resists impacts, drops, and deformation — a stark contrast to flimsy thin-walled containers, making it ideal for both transportation and daily use. Plus, the food-grade, BPA-free PET material (compliant with FDA and EU REACH standards) guarantees safety, so it won’t react with skincare ingredients like hyaluronic acid, retinol, or essential oils, preserving product purity.
