My concept was to make a storage box that doesnt look like a box at first sight and which can store multiple things like stationery. (It is a quick prototype.)

I used mount board, cardboard and paper to make this box. It is fixed by using minimum adhesive. I used origami to make the skeleton and the slit technique to fix the flaps to the skeleton of the tetrahedron.  Then, I had to make the containers inside the flap in such a way that it opens easily and is easy to store things. Also, I made a tiny tetrahedron as a cap to fix it on top so that the flaps don’t keep opening.
