The regular 3x3 Ghost Cube.

The Ghost, Virust, or Ninja, Cube is a mass-produced 3x3 shape mod. Like the Mirror Cube, one has to solve by shape, and like the Axis, Fisher, and Windmill cubes and the Mastermorphix, the middles twist.

The cube itself comes in multiple colors: black, pink, blue, white, yellow, green, etc. The stickers come in white, black, silver, gold, or a combination of those with black, although there are sticker mods where there are either random colors on each side or there is a solid color on each side.

There are other shape mods as well, such as the void, barrel, and higher order cubes (such as the 4x4 and 5x5).
