These 30mm hexagonal, smooth, black plastic bases are perfect replacements for any gaming system. The 30mm measurement is around the larget diameter (i.e. from two opposite points of the hex shape) – for clarity, the distance between two of the straight sides is a uniform 25mm.
The bases are as pictured and come with a magnet slot and the option to cut out a strip for miniature placement if required. They are the same size as 30mm bases used in game systems like Battletech.
