SuperDym C10 Extra Strong Cube Magnet in a set of 4. Designed to complement the elegantly simple glass magnetic board of the German manufacturer Sigel, this extra-strong neodymium magnet offers exceptional holding power. Its polished cuboid shape can hold up to 13 sheets of standard A4 paper (80 g/m²) on the optionally available artverum magnetic boards. Perfect for those who love to clutter a memo board with notes, postcards, and photos. Let’s be honest, with too many magnets, the design of the magnetic board often becomes unrecognizable, which is truly a shame for this stylish glass version. However, if your memory needs a little extra support or your work causes the memo board to swell, this SuperDym C10 Extra Strong Cube in a set of 4 is a great help for Sigel's artverum glass magnetic board.
