It definitely takes some practice but once you get tge hang of it, its easy. Makes my tumblerd turn out perfect!

Purchased the wrong size sleeves but kept anyway to use for something else down the road

This is quality shrink wrap, but best suited for larger tumblers (i.e. 32oz). It will work for 20oz tumblers, but needs to be trimmed about 1.5 inches from the top. Also, when using it for 20oz tumblers, the extra wrap will take longer to shrink fully around the tumbler. It works, but a smaller size would be better for 20oz tumblers. Hence my 4/5 rating. Our lessons learned: Use the low setting on your heat gun to avoid burning through the wrap while shrinking it. Always put a piece of butcher paper down on the grates of the oven to prevent the shrink wrap from melting to the metal grates.

These tumblers sub amazing! There was a small mixup with my package and the company quickly resolved for no charge! Will order again.
