Ideal for sublimation beginners.
Size: 8.5"x11"
Asub sublimation paper has been excellent for my projects. The ink transfer is very good, the colors are vibrant and defined, and it dries quickly. It has helped me achieve clean and professional results, even as a beginner. Without a doubt, it's a reliable, high-quality paper for sublimation.

Works
Size: 8.5"x11"
Works great for sublimation. Get plenty of sheets. Great value for the price. The paper is pretty thick and seems to hold a good amount of ink without smearing.
