Is the Pastel Mint 30oz tumbler completely BPA-free and safe for daily use?

Health safety is foundational to every product at Nuaims Evergreen. The Pastel Mint 30oz tumbler is constructed entirely from materials certified safe for food and beverage contact, with third-party testing confirming zero harmful chemical leaching. The tumbler body is made from premium 18/8 food-grade stainless steel (also known as 304 stainless steel)—the exact same grade used in professional restaurant kitchens, hospitals, and food processing facilities 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 (like lemon water or coffee) or alkaline. The Pastel Mint 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 bonded to the metal rather than just sitting on the surface—this prevents any flaking or contamination of beverages. The flip straw lid and all its components are made from BPA-free polypropylene (the main lid structure) and platinum-cured food-grade silicone (the straw, seals, and gaskets). Platinum-cured silicone is the highest quality silicone available—it's the same grade used in medical implants and baby bottle nipples because it's chemically inert, won't leach substances, and doesn't develop odors or degradation over time. We've conducted migration testing (following FDA and European standards) that confirms zero chemical transfer from any tumbler component into beverages under both cold and hot conditions (tested up to 100°C). For families, health-conscious individuals, pregnant women, or anyone concerned about endocrine disruptors and chemical exposure—this Pastel Mint tumbler provides complete peace of mind for daily, long-term use.
