This little mug changes color depending on the temperature of your drink.

The HARIO Furukawa factory created this cup using a special ink. Depending on the temperature of the drink, the color of the print on the surface of the mug changes.  The graphic will turn pink when hot, and blue when cold. Neat!

Hazel F. ★★★★★

I poured in hot tea and watched the mug shift from pale gray to a deep blue in seconds—the ink really is that reactive. The ceramic feels nice and lightweight, perfect for my morning coffee.

Samuel ★★★★★

The way the mug shifts from pale to deep blue when I pour in my coffee is honestly mesmerizing. It keeps my drink hot longer than my old ceramic cup too.

Stella ★★★★★

Pouring in hot tea and watching the pattern slowly shift from pale to bright is honestly mesmerizing, and the ceramic feels nice and solid in my hand. It’s become my new favorite mug for morning coffee.
