YJ Pocket Cube 4x4 M

The YJ Pocket Cube 4x4 M is a magnetic 4x4 speedcube that is a bit smaller than most 3x3s as it is only 56mm in size, this may cater to cubers with smaller hands or those looking to solve with one hand, the smaller size also means it can fit into pockets more easily. 56mm is the standard size for 3x3 speedcubes so this is essentially a 4x4 but the size of a 3x3.
