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.
