I have a small number of signed Fisher Cubes for sale. There has been several copies recently on ebay but these are the real thing made by me earlier this year. They are produced from good quality octagonal prism "cubes". The add-on parts are hollow so the puzzles are about the same weight as a standard cube. Stickers have been professionally produced for me by http://www.cubesmith.com.
The price is 85 GBP. This includes insured airmail postage to anywhere in the world. I will accept several different payment methods including PayPal. In most cases I can post the parcel the day after I recieve payment.
Please send me a private meesage if you are interested.
