Review on 🍫 Ceramic Porcelain Food Service Equipment: Sublimation Coaster in Chocolate Color by Ben Barrington

These are thicker and heavier cups. I heated up to 400 degrees in our mug press for 4 minutes - 30 minutes later the mugs were still hot. BUT - I had to keep it closed manually - I couldn't fix it while it was closed. It would require STRONG pressure to fully close and the mug would likely break. The outer circumference of the mug is 11.5 inches. My largest machine has a maximum size of 10 inches, so I wouldn't be able to print on such a large area either. Not the cup's fault, and the picture matched perfectly. But pay attention to the size! The cups are smooth as glass - I've had some other brands that were uneven etc - they were perfect.
