Gem stone shaped box, consisting of two identical polygonal pyramids, glued together at their bases. It‘s a real box that can used for packaging. It can be stored (and shipped)completely flat. When you pull the two apices (‘tops’) apart, the box will get it‘s full shape. It‘s easiest to glue this shape when both halves are flat. Just fold the glue tabs all the way in an glue the top to the bottom. Just remember not to glue the rounded flaps.
