Shrink Wrap Sublimation Shrink wrap.
You will get 10 sleeves of Shrink Wrap
These are white in color and made of plastic They are a sleeve, so you slide your tumbler in.
These are on the thinner side and take a little to get used to. Because they are on the thinner side you have to make sure you don't over shrink them onto the tumbler so there is room for shrinkage in the oven. Hope that makes sense.
