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

The first one I used bubbled up so I had to take it off and put a new one on it. The second one also got a bubble but I was able to smooth it out before the ends were shrunk too much. Would reorder.

The shrink wrap melted to my sublimation over grrr

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.

First of all the heat gun was barely blowing and not at the high temp and it immediately started to make burn holes in the wrapper exposing the sublimation paper I had underneath it. I figure I would still just put it in the oven to sublimate my tumbler. Then it melted onto the silicone mats. When we took it out of the oven to unwrap it, the rest of the wrap had more holes throughout it and the wrap literally became hard plastic chunks that you had to literally take something to chip off the pieces of the plastic just to get to the sublimation paper to take off the cup. You can see the bottom of the cup has hard burn plastic pieces on it and as I took a little pick to pop off the hard pieces it would pull off the paint as well.

Son fáciles de usar y se encogen rápidamente y firmes para que tu sublimación quede perfecta muy recomendable las volveré a comprar seguramente.

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.

These are such poor quality, they completely melted into the cup, had to throw it away.

I got these in hopes I could do some 30 oz tumblers...I did the normal process and this thing melted to the tumbler and NOTHING will get it off...wasted a tumbler. If anyone has any tips that would be great.

Very tight compress. Tumblers come out perfect every time.

I was frustrated at first because the instructions arent very good. After looking at a lot of Youtube videos and ruining 2 tumblers, I figured it out. You cant let the shrink wrap touch the tumbler. I used copier paper to protect the tumbler because the sublimation paper didnt cover the entire mug. Then I put the shrink wrap over the paper and put it in the oven for 6 minutes at 350 degrees.
