Our MagFlex sheets with brightly coloured laminated PVC fronts are ideal for creating signs and are available in white, red, black, yellow, green and blue. Each sheet is magnetised with a striped north-south magnetic field giving a secure grip. What's more, each sheet can be rolled to a 1/2 inch (12.7mm) diameter without cracking and of course, each sheet is made from non-toxic material. These MagFlex sheets are not suitable for sticking 'hard' permanent magnets too as the strong magnetic field will realign the magnetic particles in the sheet, significantly weakening its own magnetic field. If you are looking for a flexible sheet to create a magnetic surface for 'hard' magnets, then you should use our ferrous sheet and tapes.
