In addition to a dissertation and statements, you also need invitation cards to invite friends, family and colleagues for the defense, the reception afterwards and perhaps a party. It has now become a tradition for the dissertation to be accompanied by a bookkeeper. The bookkeeper is at the same time the invitation to the defense and the reception of the promotion. The bookmakers are printed free of charge by Studio Thesis. With the Plus package, the bookkeepers are also designed in style with the cover of the dissertation. Next, they are pressed with the cover of the proof sheer, so that they have the same color and cardboard type.
