Is the Blush Pink 30oz tumbler completely BPA-free and safe?

Health safety is non-negotiable at Nuaims Evergreen. The Blush Pink 30oz tumbler is constructed entirely from materials certified safe for food and beverage contact, with comprehensive third-party testing confirming zero harmful chemical leaching. The tumbler body is made from premium 18/8 food-grade stainless steel (304 stainless steel)—the exact same grade used in professional restaurant kitchens, hospitals, food processing facilities, and high-end cookware worldwide. This stainless steel contains 18% chromium and 8% nickel, which creates a naturally occurring passive chromium oxide layer on the surface that prevents corrosion and ensures the metal remains completely inert—meaning zero metal ions leach into your beverages whether they're acidic (lemon water, coffee, fruit juices) or alkaline. The Blush Pink powder coating on the exterior is a polyester-based finish that's completely food-safe, containing no BPA, no lead, no phthalates, or other harmful substances. Powder coating is applied electrostatically and heat-cured, creating a finish that's molecularly bonded to the metal rather than just sitting on the surface—this prevents any flaking or contamination.
