Best sublimation tape
Number of Items: 4
This is the best sublimation heat tape I have found. I started buying bigger rolls of it as I bought these smaller rolls when I first started. Stick and hold good works well

Reliable Product

Tape works great with no residue or coloring left behind after heating. Just wish there was more to each roll.

Residue free, Long lasting
Number of Items: 2
Works pretty good, it sticks to polo tshirt polyester material better than the inside of fleece hoodies. One roll lasts me for a bunch of clothing pieces. The tape didn’t leave any residue on clothing.
