This is a great item to add to your self bondage tool box. It is a simple tool by which you can lock away a set of keys until you can solve the puzzle and escape. Place a set of keys in the tube and fit the two pieces of the puzzle together. Once you have tied yourself up and secured your restraints with padlocks, releasing the keys will be your only means of escape! You will need to twist and turn the two parts of the puzzle until you have managed to separate them, thereby freeing the keys and allowing yourself to unlock the padlocks.
Please be careful. While bound, this is not an easy puzzle to solve. It gets increasingly difficult with more restraints and gags or blindfolds. If you want to make the puzzle easier on yourself, you can trace the path with a pen that the puzzle must twist, which will make it simpler to figure out how to open the tube. (See the last two pictures, which show markings on the puzzle to make it simpler).

Inner diameter of tube is 33mm.

**Remember to always practice self bondage with others present**
