Made with super-cool thermographic ink—an ink that reacts to heat—the Battery Morph Mug from Kikkerland shows you just how much charge your beverage has left! Pour coffee or tea into this fun design and the battery turns green, showing you what’s in the mug. As you drink your beverage the battery level drops, telling you it is time to recharge your cup.
Includes 1 mug. Created by Kikkerland, where creativity runs rampant and even the most utilitarian gadget becomes a delightful discovery.
