This set of rare-earth magnets are ideal for modelling, with three different sizes ready to take on any task – ideal for magnetising weapon options on military models. To separate magnets gently push from the side and lift away from the edge. Once the magnet has been separated it can then be handled with tweezers for accurate positioning when gluing into place. Neodynium magnets are very strong and should be handled with care. High grade N52 neodynium magnets Sizes: 20 x Large (5mm x 3mm) 30 x Medium (3mm x 2mm) 50 x Small (1mm x 1mm)
