Take a tumbler.

Animal, vegetable, or mineral? This pretty ceramic tumbler has a secret up its sleeve (it is double-walled after all!) Not only does it keep your tea, coffee, lemon water (you name it) at hot or cold temps for up to 90 minutes, but it also purifies drinks instantly. “Tourmaline” is a fancy word for the only known mineral to carry an electric charge which allows for more absorption of water into the human body—that means it’s thirst-friendly and earth-friendly. What a deal.
