great for sublimation for shirts, tumblers and also fast delivery
Number of Items: 4
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.

A must have
Number of Items: 2
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.

Great heat tape
Number of Items: 2
This tape is thicker and a bit more rigid which makes it easy to handle. It tears cleanly and doesn't wrinkle or fold over on itself when you're trying to place it. The adhesion is great. It is strong enough to hold sublimation paper and vinyl securely on any item, from tumblers to t-shirts, without any lifting during the press. It comes off cleanly every single time and leaves no residue or color marks behind.

Heat tape
Number of Items: 4
The tape works well the only issue that I have is being that it is wider it does not stretch well, while wrapping my tumblers for sublimation, other than that it is a really good tape.
