This super cute pyramid box is easy to make and looks different from the traditional square or rectangle boxes. This looks especially cute when the box and the lock are done in contrasting colours. It would make an ideal gift box for presenting chocolates and other small things. Just add a string/loop at the top and you have a lovely box that can be hung from a Christmas tree perhaps.
A possible variation for the lock is Tomoko Fuse's stopper from the variety of stoppers from the book 'Home Decorating with Origami'. I have used the heart shaped stopper.
