Teen boys can be very challening to purchase non food stocking stuffers for. I got this for my nephew spending his Christmas break with us this year between college semesters. He likes to tinker with repairing things but doesn't have a lot of tools at college. This is perfect. It has several tools in one and even comes on a keychain. Best of all, it is a snowflake, so it will remind him of our midwest winters and his family who loves him.
