This is a sublimation tumbler heat press in a variety of colors! It comes with a sleeve that fits 20 oz sublimation tumblers.
We have found best results with pressing at 380 degrees F for 25 seconds, rotating the tumbler 1/3 of a turn, pressing another 25 seconds, rotate another 1/3, then press a final 25 seconds. This will give you an even coloring all the way around, no faded spots.
You should get an infrared heat gun thermometer and periodically check the actual temperature of your heat sleeve. We have found sometimes that the actual temperature is 20-30 degrees higher than the reading on the LCD display. Try to keep it at 380, so you would set the display temp to 350-360.
