It is extremely weird how excited I became when trying this tape out for the first time. I can't speak for all of the blue heat tapes but this one in particular is all sorts of great to use. Thicker, easier to tear, stronger adhesive than the brown and clear heat tapes I've tried. I started with the clear because I was afraid of the other colored tapes leaving marks on my substrates. The clear tape was a good amount of thickness and easy to tear and use but the adhesion was terrible. I would wrap it around the rim of tumblers, fold it down into the inside of the tumbler and it would pop right back up. Forget using it on any fabrics, did not hold sublimation sheets down to totes, shirts, mousepads, at all. The brown tape I used had better adhesion but was thin and stretchy? floppy? Didn't know this was even an annoying thing until I moved on to this blue tape and was just blown away. Still blows me away how it was cheaper than the other two kind but is the thickest and best gripping of them all. So far it does not leave any marks on any of my items. I'm so impressed by this tape that I still NOTICE it everytime it's tearing off perfectly or holding my things together so well.

This tape works great for my sublimation tumblers and shirts; there is no glue residue that is left behind. It gives my tumblers a good seal at the top and bottom and down the side where I don't have air gaps in my picture I want to sublimate on the tumbler. It is durable, and it does not smell. It is easy to use and cut. It is a great value for the money and it was delivered the next day.

This tape is perfect! I’ve been using other types and nothing compares to blue tape. It holds well and is nice and wide. I’ve had no problems with it. Price is right as well.
