Discover how a lock with this transparent model! (WITH VIDEO)

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:
