Windmill Bar St. John Color-Changing Mug — 11oz Souvenir Coffee Cup

This 11oz color-morphing mug brings a small island surprise to your morning routine. When cool, the glossy white surface shows a subtle outline of the Windmill Bar design; pour in a hot drink and the turquoise lettering and ukulele motif blooms into clear, vibrant color against the white interior and black exterior rim and handle. It feels light and familiar in the hand, and the heat-reactive reveal adds a playful, nostalgic moment—like a warm wave rolling over a St. John memory. Use it on slow mornings or while planning the next trip to the U.S. Virgin Islands; the design speaks to people who collect travel mementos, love seaside music nights, or want a cheerful pick-me-up between sips.
