I Exclusively Use ONLY Hiipoo Products - Simply the BEST!
Size: 120g 8.5" x 11"
I'm just about to purchase this product for the 3rd time. I simply cannot believe how well this product works for me. In the past, I had a $2k Ricoh sublimation printer, using Sawgrass ink, and specialty sublimation paper. That expensive Ricoh printer didn't last over 2 years. I took such great care of that machine, and it was terrible. Now, I use an Epson-2800, and I ONLY USE Hiipoo ink and paper, because it is THE BEST! Hiipoo inks work excellent in Epson printers, but you must initially start with their ink, you cannot add the ink to whatever you already have in your printer. This paper is compatible with Epson printers. I will exclusively only use Hiipoo products. The quality is unmatched. The performance is superior. The value is outstanding. I HIGHLY recommend Hiipoo products. I am not a paid spokesperson, not do I receive compensation for this review. I just own a business that provides laser engraving and sublimation printed items. You cannot go wrong using this sublimation paper. Buy their inks too, the quality of the printed items are exceptional. Excellent thickness of paper. It's durable, dries quickly and the color quality is excellent! Love Hiipoo products!!!

Great paper!
Size: 120g 8.5" x 11"
I love Hiipoo sublimation paper!Colors come out crisp and clear. And so bright and beautiful! The pattern on the back is a real big plus also. This paper is great quality, not flimsy, thick enough that it's easy to use and printers don't have problems picking it up.
