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.

PERFECT HEAT TAPE
Number of Items: 6
Love this heat tape - it's clear so no worry about color transferring to products from heat transfer, very functional for these uses. I have ordered this several times and this is my product of choice for my sublimation needs. Sticks well to product, no residue left on products, easy to use, easy to remove after use, very durable for sublimation use.
