Teflon Sheet Heat Press Machine Protector - 16 x 21

I have used the teflon sheet a handful of times with my Cricuit heat press. I've made five shirts for my toddler and have used this teflon sheet protector on top of the HTV. It works as it should. I was expecting the sheet to come in flat packaging as it looks in the picture, but it does not. Instead, it came in a very sturdy cardboard tube. That may be my only issue with it, as I had to unroll it and it still curls a bit.
