The library network of the province of Barcelona needed a durable, resistant and protective bag with a capacity to withstand books. The purpose was to distribute it among library readers and library service users. It was requested to convey a timeless and cultural image. The same users would advertise the service.

We wanted to convey the maximum with the least elements; a bookcase where the letters are the books. There were two models: one for the library service and the other for the library.
