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

I used to use a mug press for my tumblers but I had trouble with uneven heat and pressure so I decided to try the convection oven and shrink wrap method and Im so glad I did. These sleeves are super easy to use and give me even pressure all over.

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

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

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.

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.

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.
