I bought this curious transparent lock which shows how the mechanism works latches. Very interesting.
It works just like an ordinary padlock. Although a little looser to be acrylic.
You can see the mechanism perfectly. Very cool.
It comes with two keys, although a bit sloppy.
See the video I made with the product:
The price is pretty cool. Can you use tools to open locks to see which is the best strategy. I leave below link to the product:
