A heat-reactive vessel for the darkly devoted. This 11oz ceramic mug reveals custom designs when warmed, then fades back to its stark black exterior and white interior as it cools—a visual metaphor for transformation and duality. Crafted from lead and BPA-free ceramic with a glossy finish and ergonomic C-shaped handle for a secure grip. Perfect for morning rituals, late-night contemplation, or as a gift that embodies the gothic aesthetic. Hand wash recommended to preserve the heat-reactive surface and longevity of your design.
