OTBS Color-Changing Mug — "On the Brighter Side" Inspirational Heat Reveal Coffee Cup

This 11oz color-morphing mug brings a little surprise to every hot drink. At room temperature the design sits softly, then blooms into vibrant, full-color artwork as warmth fills the cup—revealing bright, cheerful lettering and playful figures that lift the mood. The glossy finish gives the wraparound print extra pop, while a black exterior and white interior create a modern contrast. Durable ceramic, microwave-safe convenience, and lead- and BPA-free materials make it an everyday companion for morning routines, cozy breaks, or shared moments at the office. Hand-wash recommended to keep the heat-reactive effect looking fresh longer.
