At room temperature the mug’s black exterior keeps the design subtle and mysterious; pour in a hot drink and a crisp white, chalkboard-style graphic fades into view across the glossy wraparound surface. Lightweight ceramic with a white interior and black exterior gives a clean contrast that suits desks, labs, and cozy kitchens alike. The heat-sensitive coating reveals the artwork in seconds, turning an ordinary coffee break into a small reveal that sparks conversation. Durable printing keeps the lines bright and clear, and the mug is microwave-safe for quick reheats (hand washing recommended to preserve the coating). Lead- and BPA-free for everyday use.\u003cbr\u003e\u003cbr\u003eProduct features\u003cbr\u003e- 11oz ceramic mug with black exterior and white interior\u003cbr\u003e- Heat-sensitive color-morphing design reveals artwork with hot liquids\u003cbr\u003e- Vibrant, full-color wraparound print with glossy finish\u003cbr\u003e- Microwave-safe; hand wash recommended to extend coating life\u003cbr\u003e- Lead- and BPA-free, one-size item\u003cbr\u003e\u003cbr\u003eCare instructions\u003cbr\u003e- Hand wash only\u003cbr\u003e","brand":"Printify","offers":[{"title":"11oz","offer_id":49547046158474,"sku":"14669589742878719056","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/6211\/7258\/files\/14885128955396281699_2048_89f4a001-d3de-46b6-a447-389dd23e6f88.jpg?v=1781480417","url":"https:\/\/enforge-designs.myshopify.com\/products\/copy-of-color-changing-mug-funny-probability-p-np-design-11-oz","provider":"Enforge Designs","version":"1.0","type":"link"}
