The Z Mini 3x3 Keychain cube measures just 3cm across, making it almost twice as small as most conventional 3x3 cubes. It is extremely lightweight, and it comes with vibrant fluorescent stickers pre-applied on the black plastic version. For such a small cube, it features a robust internal mechanism and turns smoothly.

The Transparent version features transparent stickers. The Glow in the Dark version appears transparent blue, and it glows blue in the dark.
