Upgraded Split Design: Our heat transfer mug is specially optimized for 40 oz sublimation mugs with handles. It adopts a split design to transfer heat energy more comprehensively to the mug surface. Upper part size: 170×285 mm; lower part size: 80-74-82 mm.

Preheating Instructions: Please wear gloves to avoid burns. [1] Set the desired temperature and time; [2] Place the sublimation mug with heat transfer stickers in the preheater; [3] When the set temperature is reached, the machine will automatically start the countdown; [4] When the countdown is completed, the machine will beep; After the cup cools down, it can be taken out.

Heat-resistant and enhanced safety guarantee: Our heat transfer mugs can remain stable even at temperatures up to 240 degrees Celsius, ensuring a clearer and tighter transfer pattern. For safety reasons and to extend the life of the heater, do not operate the machine without the sublimation mug installed.

Adjustable temperature and timer: When you close the handle, the timer will start automatically and a prompt sound will be emitted when it is completed. In addition, you can fine-tune the diameter of the cup by adjusting the pressure knob to ensure that the heating element fits perfectly with the surface of the sublimation cup.
