Obviously it's necessary to pick a lock only when you are a locksmith or have been kidnapped and held hostage in a locked room. Or, I guess, when you need to break into your ex-girlfriend's (aka Heart of Blackness) apartment to retrieve the diamond bracelet, which you gave her before noticing the color of her heart, and which she refuses to return, so you can present it to your new, non-black-hearted girlfriend (aka She-Ra: Princess of power). And in all three cases Maker Shed's Lockpick School in a Box will equip you with the know-how and finger dexterity to conquer the task.
This desktop school is intended to help the beginning locksmith hone the skills needed to master pin-tumbler lock picking. It includes 5 lock cylinders that progress in difficulty from a single pin set in place to a full number of pin sets. The School in a Box also includes a key, 4 picks, 1 tension tool, and an instruction manual, all packed in a wooden stand.
