An object which appears impossible! ...but is not. Made of high quality precision cut aluminum, this dandy little object practically begs to be picked up and played with.

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.
