Practical for the interchangeable labeling of iron-containing shelves in warehouses or sales areas. Also suitable for schools, offices, basements, kitchens, or whiteboards. The front side is plastic-coated, while the back side is magnetic. Here's how it works: Cut the labeling tape, write on it, and attach it to an iron-containing surface – done. It can be labeled with non-permanent markers and wiped off after drying. The length can be individually adjusted with regular scissors. The adhesive strength is 42 g/cm². Warning: This product is not intended as a base for attaching magnets.
