Think outside the box - solve the puzzle!

A fantastic puzzle, brilliant in it's simplicity - can you open the box?

This simple yet complex puzzle features a small 4in x 5in wooden box. The aim is to simply think outside of the box in order to open the box - not as simple as it sounds! The solution can only be found online, so there's no sneaking a look at the answer. Once you have solved the mind boggling puzzle, why not put a little something inside the box, give to a friend and (smugly!) see if they can find the gift cleverly hidden inside. Suits any age from 6 to 600...and No, the Elves here didn't open it quickly...but the 10 year old did!
