Hello, sunshine! Reject single-use plastic and express your individuality with our Tang Yellow reusable bottle. No nasties; just 18/8 (304) grade stainless steel, double-walled, and vacuum-insulated which keeps liquids hot for up to 12 hours and cold for up to 24. Yellow Lids bottles are all leak-proof too - we love ocean waves, but not in your handbag! With our gorgeous powder coating, they're sweat-free and beautiful to hold too. You're so planet friendly!
