The Haselgrove box is a unique puzzle based on the locking mechanisms of the Egyptian pyramids. The object is to "open" the box. There are a series of moves you will need to make to release the locking mechanism. Since you can't see inside the box, you must essentially solve it blind but listening to sounds as the blocks move around inside. Once open, you’ll notice that the larger piece viewed sideways on, is in the shape of a J while if you look at the top face it takes on the shape of a letter H; The initials of its British inventor, Jennifer Haselgrove.
