Happy to find a seller that carries the 120
Size: 8.5"X11"
I’ve been doing sublimation since May 2025. I have tried a variety between 105, 120 and 125. I’m not exactly sure why 120 ASub it is becoming harder to find . I absolutely love it. When I make my stainless steel tumblers, my colors pop more with 120.

Great Sublimation Paper – Perfect for Mugs
Size: 8.5"X11"
I purchased A-SUB Sublimation Paper 8.5x11 Inch 120GSM and I’m very happy with the results. The colors transfer beautifully. I used it for sublimation mugs and the print came out vibrant, sharp, and very professional-looking. No fading, no dull colors. I also tried using it for a cap, but the issue was not the paper — my cap heat press machine didn’t perform well and the transfer failed. For mugs, this paper works perfectly. Highly recommend for mug sublimation projects.

Recommend
Size: 4x9.5inch
First, the sizing is absolutely perfect for these projects. Instead of wasting large sheets and having to cut them down, these pre-cut sizes save a ton of time and effort — and most importantly, reduce paper waste. The quality of A-Sub paper has always been excellent: it holds vibrant colors beautifully, releases ink consistently, and produces crisp, sharp designs. Both of these sizes continue that tradition. I’ve noticed my images transfer smoothly and evenly every time, whether I'm working on ceramic mugs or glass tumblers. In terms of value, these smaller sheets are definitely worth the price. You get professional-quality results without using more paper than you need, which in the long run saves money and materials. Overall, I highly recommend these A-Sub sublimation papers for anyone looking to streamline their mug and tumbler production. They’re efficient, reliable, and a great investment for any sublimation business or hobbyist. - send me stuff to review.
