100 PCS Sublimation Shrink Wrap Sleeve 5x10 Inch White Bags for 20oz Skinny Tumbler, Heat Transfer Shrink Wrap Film

It keeps the image tight for heat pressing. Works just fine.

These kept sticking and tearing

The first time I bought these, they were PERFECT. They shrunk very well and was super easy to remove. Now, the last 2 times Ive purchased, they are too thick, they are difficult to remove, the perforated line does NOT work to remove it, and its a waste! I will be returning them!

I was really looking forward to getting and using these since the price was so reasonable for how many you get. However, the first one that I grabbed out of the package came apart at the seam. I thought that maybe it was just one, but it ended up being about 90% of the package that did it. I had to tape every single one in order to use them so they didnt fall apart when the heat hit them. Very frustrating!!!

These tumblers you sent me where not sublimation we used half to start and didn’t sublimate.. now it’s too late to return

My cups have turned out great while using the shrink wrap.

This stuff is nothing more then junk If you want junk then this is the product for you. It melts to the tumbler and sucks to get off. Save your money and buy something else.

Pensé que eran las más anchas pero le sirven a los squiny

I tried 5 sleeves and every one melted at 340° and melted to the sublimation glasses. I sadly cant recommend these.

The heat shrink melts while backing the tumblers, which makes it incredibly difficult to remove from tumbler, which also makes the tumblers more prone to chipping while trying to remove the heat shrink from the mouth of the cup.
