Sublimation Shrink Wrap Film,White 7x11 Inch Heat Sublimation Shrink Wrap Tube for Mugs, Tumblers,Blanks, Shrink Wrap Bands for Sublimation,50 Pcs

Horrible! They melted when putting them on huge holes and when I got one to shrink to the cup the cup didn’t come out right.

Still trying to get used to them but works great.

Im so disappointed in these. They should not be used for heat sublimation as the temperature is too high for this product. It literally melts off and drips like liquid plastic. Id love my money back to be honest.

Great

These tumblers sub amazing! There was a small mixup with my package and the company quickly resolved for no charge! Will order again.

These are way too big for 20oz tumblers, it pretty much melted and bubbled off during heating process. Def won’t be buying again.

Don’t waste your money. No matter how light I applied heat .. holes appeared. Useless shrink wrap! If I could give it a zero, I would.

Gave it a try to help me with my tumbler press. When it shrinks the plastic rips and melts. Its melted down it gets brittle and have to peel it off the cup. Maybe it works in the oven but in a tumbler press it fails. Total garbage imo

I would love to use it but the ones I got Re so big that when Im heating then to shrink it just gets all messed up with crazy lines, messed up one cup bei it ended up splitting open in middle

Works great
