Two dovetail impossible objects. The smaller 2-piece one slides apart, but has a piece chipped out on one corner. The other 3-piece is glued together (or the varnish made it stick), so it's not really a puzzle at all, just an impossible object. Both are dinged up a bit. I don't know how old they are (they look old) or where they came from. The larger one is 5" long.Postage is $7.35 in the US or $29.95 international. 

Impossible object made by Toyo Glass.  Wood arrow through a coin.  Includes original box, which shows wear consistent with age (see photo).  Coin shows some oxidation from age.-----Buyer is responsible for shipping which should be less than $10-12 for small puzzles (within USA, first-class).  Priority mail (and heavier items, such as the glass puzzles) might be $3 to $6 more.  I charge only exact shipping costs.  Please contact me if you need an estimate for international shipping.  If yo...

Triple Dovetail Triangle is number 3 in Robert Rose's MBP (Mental Block Puzzle) series. Robert sold a bunch of his puzzles at IPP 23 in Chicago and, sadly, passed away before being able to attend another.This puzzle is in perfect condition with no fading of the vibrant turquoise and pink anodising. It is by no means a difficult puzzle and should be considered an impossible object rather than a tricky puzzle. It does make a brilliant fidget toy and displays beautifully!***************************...

Interesting mechanical oddity

This is a really unique piece that was designed by Oskar van Deventer and Wayne Daniel, produced by Wayne and gifted in the IPP29 exchange by Stan Isaacs.It has the super-interesting aim of balancing the puzzle off the end of a table or shelf but you need to try and solve it initially without multiple tries.It is a very clever design and one I failed at!Definitely a collector piece.Shipping is sent tracked and combined shipping is available.

You don't get huge numbers of impossible object puzzles at IPP exchanges but this is one of them. A steel ball forever trapped in a poplar cage with no way to escape and no (easy) explanation how it got in there. The puzzle comes in it's original box with a number of humorous solutions on the accompanying information sheet (in English and on the reverse in Japanese). This was, of course, Robert Sandfield's exchange puzzle at IPP 24 in TokyoI've marked the function as perfect, neither too loose n...

Impossible Chain was Saul Bobroffs exchange puzzle at IPP25 in Finland, 2005.This puzzle is impossible to take apart (in a non-desctuctive way), but how was it posible to put it together... or was it not possible at all?The goal is to imagine how this impossible chain was made out of 2 zebrawood ring/block pieces and 4 silicone rings that have no seams. Even on very close inspection this seems impossible!= = = = = over 70 IPP25 exchange puzzles available, see my other listings = = = = =
