CSAO is a shop that has items from Africa made out of recycled materials. On some of the products, maybe all of them, money goes to a foundation that helps street children. I didn't see the "no photos sign"...so here are the photos I took. See the tube on Centre Pompidou made of water bottles? They were perfect for that. The shop is on Elizavir st. not too far from the Picasso museum, in case you want to stop in there.
