Size: 2 inches wide x 3 inches tall. I found a good supply of these plastic see-thru padlocks for practice lock-picking on. I like practicing on padlocks because they are easy to hold in your hand and use the tensioner with one hand, and rake or pick with the other. Good way to practice seated without having to put the practice cylinder in a bench-vise or hunch over at at door all the time. These are a little cheaper than the other kind we carry too, so it makes lock-picking a little more affordable to learn! Good instructional tool to talk to your guys about padlocks and how they work too. The first step in defeating the enemy is knowing the enemy. Plus....the padlock really works! It comes with two keys and the lock is functional and lockable. I wouldn't secure the crown jewels with it, but it would work for your locker at the station or something similar.
