The Magic Mug Black is an 11oz heat-sensitive colour-changing ceramic mug that starts completely black when cold — and the moment you pour in a hot drink, your custom design appears in full, vibrant colour. This reveal effect makes it one of the most exciting and gift-worthy sublimation blanks available, and it sells itself the moment a customer sees it in action. Made from lead-free, cadmium-free food-grade ceramic with a full polymer sublimation coating, it presses cleanly at 200°C for 150–180 seconds on any standard mug press machine. It’s a strong seller for personalised gifting shops, birthday and anniversary gift businesses, corporate merchandise, and print-on-demand e-commerce stores — especially for customers who want to gift something that feels truly special and interactive, not just a printed mug. Compatible With: Mug press machines and 5-in-1 / 8-in-1 combo heat press machines (mug attachment) Sublimation ink printed via Epson EcoTank or compatible sublimation printers Sublimation transfer paper (standard A4 or A3 sheet format) Full-wrap sublimation designs (design prints on the heat-sensitive coating layer) Personalised gifting, corporate giveaways, event merchandise, and retail drinkware collections Bundling with Frosted Mug 11 Oz, Frosted Beer Mug 16 Oz, and standard white sublimation mugs for a complete mug range
