8x12 Inch Sublimation Shrink Wrap Sleeves, 60 Pcs White Sublimation Shrink Wrap for Tumblers, Mugs, Cups and More

These sleeves were perfect for sublimating my beer can coolers. They are easy to apply & do well with the heat

Worked perfectly just need to cut the plastic to fit the size of your product

These are awful. They melt and bubble at temperature above 300. Sublimation requires 350-400 degrees to even work, so these are useless. Hard to get them to even shrink to the cup with a heart gun without melting. They also stick to the cup and are impossible to remove.

Have not actually used these to wrap a Cup, Mug or Tumbler yet but when I hold them in my hands they are nice and think and you can just feel the quality with which they are made. Ill update this review once Ive used the wraps but I expect my Sublimation projects to come out beautifully with these aides.

Very tight compress. Tumblers come out perfect every time.

They melted at 350. Actually, they started melting with just my head gun.

This stuck to the tumbler and won’t come off. The bottom and top edge of the tumbler didn’t have sublimation paper on it, so when I stick the whole assembly in the convection oven, this stuff shrunk more and permanently fixed itself to the parts of the tumbler that were bare.
