SHRINK WRAP for 12 oz kid tumblers for sublimation. Clear. Tumbler NOT included. Also fits SKINNY can holder metal blanks. REMOVE THE PLASTIC LID BEFORE SUBLIMATING. Use a heat gun to shrink wrap the tumbler completely after the transfer has been taped well to the outside. Then sublimate in a convection oven. Times vary due to differences in convection ovens, but a starting reference is 400° for 6-7 minutes. Test your own equipment for best settings for you.
