I love this tape for the width and the fact that it doesn’t leave residue. It’s also easy to remove when you are peeling it. (For both tumblers and shirts) The only issue I have is that when you are trying to tape tightly on a tumbler, it doesn’t always adhere tight so often times it snaps off of tumblers when pulling it to stick.
