But another thing he had done was to take a bunch of door locks and mount them into a board in a 3 x 3 arrangement (9 total locks) and removed pins so the first lock was 1 pin the next lock had 2 pins, etc up to 7 or 8 pins. Then you could practice picking them from easy (1 pin) to hard (8 pins). I found that to be a really clever thing and if you know someone who is re-keying their house or for some reason decides to replace all the locks, you can often get those from the locksmith doing the work.
They sell a re-keyable pin tumbler lock that comes with a variety of different pins so you can practise increasingly difficult configurations as you learn.
I don't know if they will refuse to ship to jurisdictions where laws are tighter.
They definitely don't care about our laws. Worst case scenario is customs snatches them, but that seems unlikely.
