YJ ZhiLong Mini (56mm) 4x4x4 Magnetic is a compact magnetic speedcube design. The “56mm” refers to the size of the cube, specifically the length of its edges. This makes it smaller than the standard 4x4x4 cubes, which are usually around 60mm or larger. The smaller size can make it more comfortable for some solvers with smaller hands or those who prefer a more compact cube.
