These cubes are made of multiple layers of red acrylic glass. A 5x8 mm rod magnet with an adhesive force of approx. 1 kg is embedded in the centre of the cube. Not only are these magnets fun, they also stick very well! Six A4 sheets of paper or a normal postcard are no problem for these magnets! These magnets are made in small quantities by the Transmet Werkstatt in Wil; the Werkstatt provides working and learning opportunities to job-seekers.
