Magnext is a magnetic construction toy consisting of plastic building pieces containing embedded neodymium magnets, steel bearing balls, and a variety of additional parts which can be connected together to form anything from skeletal geometric shapes and structures to more robust and functional toys. Rather than the rods of Geomag, Magnext has 'triangular' and 'square' pieces with 3 and 4 embedded magnets. The balls are 0.59 inches in diameter (larger than the 0.50 inch balls of Geomag).
