Heat shrink bags are a key component for sublimating drinkware and other items that will be decorated in a convection oven. Once heated, the heat shrink conforms to the item creating firm even pressure of the sublimation transfer.
The heat shrink bags are able to be used without a heat gun - just place your item inside the bag, tuck the top of the bag inside your cup or mug, then place in the oven.
The 6.75" x 11" heat shrink bags are perfect for skinny tumblers!
