This tape is magnetic on one side and adhesive on the other, so, depending on the spot you choose, you’ll have to use either one or two pieces of tape (as you can see in the video).
You don’t need scissors to cut a piece of tape, you can do it with your hands; it’s really simple and easy to do. Choosing what you want to hang with the pieces of tape might take a bit more effort.
You can use the tape on iron, glass, plastic... The back of the package has a list of all the surfaces you can use the Magi Mags magnetic tape on.
