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.

My go-to sublimation paper for crafting
Size: 8.5"x11"
I've used several sublimation papers, and this one has worked really well for my crafting projects. The colors transfer bright and vibrant, and the images come out crisp with good detail when using the proper sublimation printer and ink. The paper feeds smoothly through my printer and feels like a good quality weight—not too thin and not overly thick. I've used it for tumblers, keychains, and other sublimation projects, and I've been happy with the results. I also appreciate getting 110 sheets in one pack because it lasts a while, especially when working on multiple projects at once. Overall, this is a reliable sublimation paper that gives consistent results and is great for crafters or small business owners.

Great paper good price
Size: 3 Reams | 1500 Sheets, Style: Letter (8.5x11)
This is a solid everyday paper option that does exactly what it’s supposed to do.
The packaging was good—everything arrived in perfect condition with no bent corners or damaged reams. It’s nice not having to deal with warped paper right out of the box.
Printing quality has been consistent. I’ve used it for both home and work printing, and it feeds smoothly through the printer without jams. The brightness is good too—text comes out clear and sharp, and colors look decent for standard copy paper.
Overall, it’s reliable, good quality paper at a fair price. I’d definitely buy it again.
