JUST FUNKY My Hero Academia Heat-Reactive Color-Changing Mug 16 oz — Ceramic Character Reveal, Hand-Wash Care

This JUST FUNKY 16 oz My Hero Academia heat-reactive ceramic mug reveals extra Class 1-A characters when filled with a hot beverage.

Celebrate your love for My Hero Academia with a collectible mug designed to change as your drink warms it. The printed artwork initially highlights two central heroes — Izuku "Deku" Midoriya and Katsuki Bakugo — and then unveils more classmates when heat activates the color-changing coating. Built from durable ceramic and sized for everyday use, this novelty cup combines fandom style with practical drinkware for coffee, tea, and other hot beverages.

How does the heat-reactive design work?

The mug uses a temperature-sensitive coating that becomes translucent when exposed to hot liquid, revealing additional artwork underneath. The transition is visual and immediate, letting you watch new characters appear as your drink is poured. Cooling the mug will return it to the original image, so the effect is repeatable.

• Thermochromic finish that changes with heat
• Initial artwork shows Deku and Bakugo; hot reveal adds Class 1-A teammates
• Reversible effect—cools back to the original look

Is this mug safe and how should I care for it?

The mug is crafted from sturdy ceramic but the special coating requires gentle handling to preserve the changing effect. Hand washing is recommended; avoid soaking or abrasive scrubbers that could damage the print. Do not use the microwave or dishwasher to keep the finish intact.

• Hand wash only; do not soak
• Not microwave or dishwasher safe
• Handle gently to protect the color-changing layer

What are the practical details — size, material, and everyday use?

This cup holds 16 fluid ounces, a common size for morning coffee or generous tea servings. The ceramic body retains heat well and is suitable for a range of hot beverages from espresso-based drinks to brewed tea. Its handle and shape are designed for comfortable sipping and routine use.

• 16 oz capacity for larger servings
• Made of durable ceramic for heat retention
