An object which appears impossible! ...but is not. A lovely two-piece aluminum puzzle. Try to separate the two pieces. Of course, they're dovetailed together, so any direction you pull, the pieces are thoroughly locked in one another... the elegant mechanism is hidden inside. Made of high quality precision cut aluminum, this dandy little object practically begs to be picked up and played with. While the actual mechanism is quite straightforward, the puzzle can serve as an admiral paper weight if your efforts prove to be unsuccessful.There are three puzzles which are part of the series. All look a bit different - and each is mind boggling. Designed and produced by Will Strijbos, this puzzle is a worthwhile addition to any collection.
