The MoFang JiaoShi Mini 3x3 Keychain cube measures just 4.0cm across, making it about 2/3 the width of a typical 3x3 and a bit larger than the usual 3x3 keychain. It is extremely lightweight, and this version features a keychain. Like most cubes from MoFang JiaoShi, the Mini 3x3 Keychain turns very well right out of the box, and it features vibrant stickerless bright shades.
