In the page's words:

We want to be able to shop in our neighborhood in an environmentally conscious way - next door and without packaging. Or simply "take a break in the café next door", swap, chat and make the world a little better and plastic-free. In Munich's first unpackaged store organized as a cooperative, we comrades are all customers and traders at the same time, do business together and thus achieve much more together than each individual. Cooperatives are strong together! Whether you are a cooperative member or not, you can always shop with us. But if you want to get more involved, simply add a cooperative share to your shopping basket next time you go shopping.
