Meet a mug that reacts to your ritual. Crafted in Japan from HARIO’s signature heat-resistant glass, the Fuji Thermocolor Mug features an illustration of Mount Fuji that changes color with the temperature of your drink.
When filled with a hot beverage over 50°C, Mount Fuji turns pink, while cold drinks below 15°C transform it to blue. The subtle color change adds a unique touch to your everyday coffee and tea rituals.
A blend of Japanese craftsmanship, thoughtful design, and a little science, this mug makes every pour more memorable. For best care, hand wash only.
