COOL EDUCATIONAL/PRACTICE/VISUAL AID - SEE-THRU KEYED PADLOCK
Here is something pretty awesome . . . a padlock with an entirely transparent body that reveals all. This is the perfect visual aid if used for a teaching tool, and just as handy as a practice lock because, as you attempt to pick it, you will be able to see how the pins in the lock react to your process. Makes an ideal gift for geeks and novelty lovers.
Equipped with two working keys.
