The text from my listing is as follows.
Rubik's Tangle plastic double-sided version
The cheap cardboard 5x5 versions of this classic puzzle occasionally appear on eBay and fetch collector-style prices. This is the genuine plastic double-sided 3x3 version, Each tile is almost two inches along each edge, and well over a quarter of an inch thick. The raised ridged rope effect ornamentation is a delight to handle, and it is hard to believe that plastic playing pieces can be so tactile.
Please contact the seller for several more photographs of item. Window ledge and pen are for display purposes only and are not included in the sale.
