Great Quality!
These sublimated beautifully. I went looking for times and temps in the reviews, but not a lot of people share that information, so I want to say what worked for me. Here's what I did, and it worked great the first time. I sized my image a little bigger, 9.5 in width, and 8 in height. I then placed a thin dish towel over my image and pressed the image for 60 seconds at 400 degrees. It came out vibrant and perfectly coated the full mouse pad. Would recommend. I'll be buying again.

Great sublimation mouse pads
A-sub always has the best sublimation products in my opinion. And love the fact that they come with their own packing bags.
