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.
