Flexible Magnetic Tape, 1/2 inch x 10 feet with strong adhesive on the non-magnetic side. Great for all kinds of projects including crafts, science, education, DIY, office, etc. Peel-off liner gives you access to the adhesive side to adhere to any smooth, clean surface such as metals (steel, stainless steel, aluminum, copper, brass, etc), wood, most painted surfaces, glass, some plastics, concrete, tiles. The magnetic side of the magnet has multiple poles running down the length of the magnet which makes the magnet much, much stronger than if it was a single pole. You are only limited by your imagination on what you can do with this magnet.
