Almost perfect
Great for sublimation but it is thin. Only 0.2cm if it is 0.3cm it would be perfect. I will get 0.3cm next time. Not this one.

Fantastic color and clarity! AAA+
Work amazingly well! Sublimation print was done on Epson 170 printer. 375 degrees for 60 seconds medium press. Love it! Easy to use, superb print quality and a great value for the money. They have a nice nonslip bottom.

The best!
This is by far the best sublimation ink! I’ve tried other brands and this is the most vibrant and cheaper than most!
