Erman mug thermal effect | personalized gadgets

The Erman mug is a 300 ml ceramic item that combines everyday functionality with an engaging visual effect: the exterior, initially black, changes color upon contact with the heat of the liquid, revealing the logo or personalized message. The interior is white, while the compact size (Ø 8 x 9.5 cm) makes it suitable for use in the office, home or as a promotional gadget. Thanks to its compatibility with the sublimation technique, the Erman mug offers extensive customization possibilities: the company logo, brand colors or a promotional message can be reproduced with precision and high color rendering, emerging dramatically with each use. This surprise effect makes it particularly suitable for corporate welcome kits, events, product launches and internal communication initiatives. The available print area is 18 x 8 cm, enough to enhance articulated graphics or brand messages. The mug comes individually packaged, ready for distribution or for inclusion in gift kits. An everyday object that turns every coffee break into a moment of interaction with the brand, leaving a lasting impression.
