Unleash your inner dragon with our Color Morphing Mug, 11oz from Dragon's Library! This magical ceramic mug changes color as it heats up, revealing a cute comic book adventure on its heat-reactive surface. When it cools down, the exterior transforms back to its original black, while the interior remains white. With a generous 11oz (0.33l) capacity, it’s perfect for that big morning cup of coffee. Crafted from durable ceramic, it's a treasure you'll want to hoard and discover every day!
