The main ideea is that all of this shopping bags reperesent a piece of universe. We can put in this "micro-universe" everything we want. But as a human beings we have to be responsible about what we buy and how to menage with this products after we used  them. To make people more responsible  is the main goal of this proposal. The ideea is based on 4 primary elements of nature: earth; water; air and fire. Each of this elements, since antiquity have a geometric symbol earth-cube; water-icosahedron; air-octahedron and fire-tetrahedron. If we unfold all this perfect solids in a planimetric figure, semething like ORIGAMI, we obtain a patern which can be repeated like a puzzle.
