Designed to challenge your expectations, these trick bolts look similar to ordinary nuts and bolts, but each presents a different puzzle. We can tell you that they are 1 1/2" long, and that we make them from stainless steel in our own machine shop. Saying any more might risk revealing clues to their solution.
Of course, once you’ve figured them out, you can then share them with a friend or neighbor, or leave them lying about to trap the unwary. Simple fun, and great desk toys.
The puzzle is in very good condition.
