Bjonberry
Bjonberry is a webshop for selling and buying custom iPhone cases. Each user can act as a seller who creates his own designs and as a buyer who just wants to make his or her phone unique. Nevertheless, if a user wants to be a seller his design must be approved previously by an admin. There are a lot of already existing designs, so every customer can choose one from ready cases too. It works very simple: a user goes to the site then he can whether buy one from the collection or create a design of his own.
