Everything you need to know about your heat-changing mug.
How does the heat-changing mug work?
The mug features a heat-reactive coating. When you pour in a hot beverage, the black exterior warms up and reveals the hidden green artwork. As the mug cools, the design gradually returns to its original appearance.
What drinks can I use in the mug?
Enjoy coffee, tea, hot chocolate, and other suitable hot beverages. Avoid extreme temperature changes and follow the care instructions provided with your mug.
How do I care for my heat-changing mug?
Gentle hand washing is recommended to help preserve the heat-reactive finish and artwork. Avoid abrasive sponges and harsh cleaners. Check the product packaging before using a dishwasher or microwave.
What size is the mug?
The mug holds approximately 14 oz (415 ml), making it a great size for your everyday coffee or tea.
Will the artwork disappear permanently?
The artwork is designed to appear when the mug warms up and become concealed again as it cools. Handle and clean the mug gently to help maintain its finish.
Is this mug a good gift?
Absolutely. Its heat-activated reveal makes it a distinctive gift for coffee lovers, collectors, and fans of the show's iconic aesthetic.
