Work hard for the money

Bilz box is an alternative to the cash in the envelope (or the $12 check you get from grandma on your birthday) gift. It is a puzzle in which you can see, to your frustration, your reward the entire time... taunting you from within. Cash, check, tickets, or any paper can be slipped into the tray by the gift giver and then locked. The gift receiver must negotiate a ball through a two level maze to get the tray to open. An excellent gift holder that might be more memorable than the gift itself. The box can also be reused over and over, so someday you might get it back!
