A lock that doesn't need a key to open it! Move the metal sliders around in their grooves until you can figure out how the lock comes apart. This version is made entirely of transparent acrylic which allows you to see the maze that is happening inside the lock as you are navigating the sliders. This is the same puzzle as the original JP Lock Holz and the JP Lock Bronze, only in a different medium.

Fun puzzle. It looks amazing in my collection and the build quality is great. Just don’t expect a tough puzzle. Since it is clear, it is very easy to solve. It took me about 2 minutes.
