Color-Changing Coffee Mug — “Running on Coffee & Questionable Decisions” 11oz

Warm, playful, and just a little bit magical — this 11oz color-changing mug turns your morning routine into a reveal. At room temperature the exterior holds a sleek black finish; pour in a hot drink and watch the hidden design bloom across the glossy ceramic. The printed image keeps its detail and vivid colors thanks to modern printing techniques, while the black C-shaped handle stays comfortable in hand. It’s the kind of mug that sparks a smile during quiet coffee breaks, fuels conversational barista-level pride, and becomes part of the ritual for anyone who loves small daily surprises.
