The letterbox 3-4-5 has been in BD’s catalogue for over 30 years and has become a classic in Spanish design. Tusquets and Clotet designed the first letterboxes which were placed “in rowlock” that is vertically on one edge. This way they could offer more capacity than the traditional letterbox, visually occupying much lesser space.
