The Rubik's Void Cube is a puzzle in which the same six colors as a normal Rubik's Cube are arranged so that each side of the cube is one color. Generally, when playing with Rubik's Cube, it is the theory to grasp the color of the center of one side where the arrangement does not change, but since this product does not have that center part, it is more difficult than Rubik's Cube. Is said to be expensive.

The Speed Cubbing Kit ver.2.0 is a product that comes with a disassembleable Rubik's cube, a flat-blade screwdriver and screws required for customization, and special grease for smooth rotation. By removing the central part of the Rubik's cube, disassembling it, adjusting the screw tightening of the core part that is the axis to rotate, and attaching a ring-shaped part (metal washer), you can rotate it to your liking. Can be adjusted.
Even those who have been playing with ordinary Rubik's cubes can enjoy it by increasing the difficulty level and challenging the fastest record.
