3-4-5 Mailbox

The 3-4-5 design grew from decades of design. Lluís Clotet and Oscar Tusquets developed the design from their A Sardinel mailbox, a piece made in 1975 at Studio Per. The mailbox had a tall, narrow frame to be fitted on a sardinel like a shelved book. It visually occupied less space and could be filled from the top. The current 3-4-5 is made of steel sheets painted in black with stainless steel doors and a white labelling window. It is available in blocks of three, four and five pigeonhole letterboxes. It is installed simply by placing the various blocks against the wall.
