This puzzle is a Square-1 variant in which there are twice as many edges as before, and there are also 4 layers instead of 3. Because two edge pieces equal the same angle as one corner piece, the geometry of the puzzle is similar to an octagon. It also has a second axis for slicing, and because of this, the puzzle can also shapeshift into a 2x2 which can randomly bandage depending on the previous moves. This allows the puzzle to scramble in many, many more ways than the original version. This puzzle is sold as a DIY kit directly from Shapeways. If you choose to order this way, you will also need to get 3 M3 screws (15mm length) 3 springs, and 3 washers along with your initial purchase. Optionally you may need to purchase dye to dye the puzzle a different color if you wish. The stickers for this puzzle are also available at Oliver's sticker shop here: http://oliverstickers.com/stickers-for-shapeways-puzzles/ben-streeter/ben-s-master-square-1.html Thank you for your interest!
