Bring a reveal effect to every sip with this personalized black magic mug that changes color with hot drinks to display your photo, name, or message. The heat‑sensitive coating unveils your design when filled with coffee, tea, or milk, then returns to black as it cools. Crafted from ceramic with a comfortable C‑handle, it’s a unique gift for birthdays, anniversaries, return gifts, and corporate gifting. For best results, hand wash only and avoid abrasive scrubbers; check microwave safety for your specific batch if the coating is heat‑sensitive.
