Good quality
Number of Items: 4
Great tape for using with a heat press. It doesn’t leave any marks and comes up easy. I use it for taping down sublimation stuff and have had no issues on slate, shirts, metal or anything I’ve made it sticks well and comes off easy.

Almost perfect

Works ok, and no color to bleed onto sublimation surfaces. Not very sticky making for easy removal but sometimes a bit of a challenge to get to lay down.

I love these. I use them to wrap my tumbler before sublimating them in my sublimation oven. They work every well to let me see the process so I don’t scorch my design.
