I recognize that set, I think i know where you got them
I would like to throw in my 2¢ here and say that these picks are great for beginners. I have successfully picked a variety of low-to-mid security locks with them, including a masterlock #3 and various locks on things like bulletin boards, "luggage locks" etc... The set could really use a rake to handle modern locks, but its a great start. Dont expect to be able to pick any vehicle locks or doublesided ones without the proper rake/tools.
