These add-on pieces are designed to be glued onto a mini (30mm) Rubik's 3x3x3 cube, which are very cheap and can be found on Ebay and other puzzle sellers like lightake and witeden . They transform the 3x3x3 into a Brilicube (see http://twistypuzzles.com/cgi-bin/puzzle.cgi?pkey=1854) which is a centerless version of a 3x3x3 Rubik's Cube. This model does not includes a sticker template, but you can buy stickers from Oliver's Stickers here
; see my other Brilicube model if you want the template. I can also supply a fully assembled and stickered puzzle, please contact me for more information.
