JP Lock Bronze is a trick lock designed and made by Jean-Claude Constantin made of plexi, wood (MDF probably) and metal pins.
The funny thing about this puzzle is that you clearly see what you're doing when solving it. There are very few puzzle locks that are transparent. This one and the "open lock" by Gary Foshee are the only 2 that I know. But maybe there are others?
It requires several steps to open, mainly sliding the pieces while trying to not be blocked by the ball bearings.
Honestly this is a way too easy puzzle. It took me few seconds to open and a non experienced puzzler should be able to solve it under a minute or so. So it may be more suitable for children in my opinion.
Don't get me wrong: this puzzle is nicely crafted, great quality and is pleasant to solve!
But I expect a bit more difficulty. Of course, there are versions of it that are not transparent and I strongly advise not transparent versions for a better challenge, even if I am not super found of navigating blindly during a puzzle journey...
