Quality Paper Gives Great Results
Size: 120g 8.5" x 11"
Works well for Sublimation done thru Ink Jet Printers. Quality material and the finished heating provided great results in my projects. I used in conjunction with the Hiipoo Sublimation Ink and they made beautiful results with no issues. Thank you.

Great sublimation paper
Size: 120g 8.5" x 14"
I like using this paper and have purchased numerous times. The one I buy the paper is a little thicker and the designs print beautiful vibrant colors.

Works Very Well
Size: 120g 8.5" x 11"
I am new to sublimation printing, and purchased this based on recommendations from multiple websites. I'm so glad I did! It transfers well onto several mediums, including shirts, totes, mousepads and cups. I've never had any jams or misfeeds, and the quality of the paper is high. I'll definitely purchase again!
