Let’s talk numbers—this 46 oz Coldest Tumbler keeps drinks cold for 36 hours and hot for 13. Yes, you read that right. Ice stays ice. Coffee stays hot. It’s wild. And with three lids (straw, pop-top, and blender), it fits into literally any part of your day. Add the spill-proof design—even with the straw in—and the black and gold music notes? That’s just the aesthetic bonus. If you’re tired of lukewarm anything, this is your solution.
