There just is no other tape that can compare to or compete with Scotch Magic Tape. There are certain brands that are the best in their categories, in my mind, like Kleenex, Bounty paper towels, etc., and in the tape category Scotch has always been the very best one. I like the way it just disappears into whatever you put it onto, such as the back of an envelope to seal it. When I tear up something by mistake, there is nothing better than Scotch Magic Tape to be able to attach the pieces back together with. The paper is almost as good as new with the Scotch tape.
Scotch Magic Tape is the only kind of tape I buy. I have used cheaper tapes. They pale in comparison. Magic tape is virtually invisible when applied. It is sturdy yet able to be sliced with a fingernail when you need to adjust the length of the tape on the fly. Cheap tapes just twist and crumple. No frustration with Magic tape. Did I mention that it is the only kind of tape I buy?!
