Excellent Quality
Size: 11"x17", Size: 11"x17"
This paper is the only paper I have ever tried with my sublimation printer. I get the most vibrant colors with every transfer. I have not experienced any fading even after washing multiple times. I have purchased this paper in letter size, 11x17, as well as 13x19 for use on welcome doormats. I have not been disappointed with any. The paper feeds through my printer without issue whether I load a single sheet, or multiples. So far, I've used it to sublimate on dishtowels, garden flags, welcome mats, t shirts, sweatshirts, and mugs. I am always happy with the finished product. I highly recommend this sublimation paper, and it can usually be found at a great price. I advise you to stock up when you see a sale

Best sub paper!
Size: 8.5"x11"
This is actually my second box of this paper I purchased. I use it that much! I like it that much! It works easily through my Epson 2850. The sub ink transfers to this paper with vibrant colors before pressing. I like the ASub print on the back to help me load the paper correctly in my printer. The ink does not bleed through the paper. I like that this paper comes in a plastic bag and in a box. This is helpful to keep the moisture out of the paper. The paper is durable as I try to manipulate on my substrate.
