These ceiling lights by Seattle design studio Graypants are made from salvaged remnants of corrugated cardboard.
Named Scraplights, the range utilises material leftover from the studio's production of cardboard furniture plus reclaimed waste from the local area.
The cardboard offcuts are laser-cut into concentric circles to maximise use of material before being stacked and glued together by hand.
Four different shapes of shade are available.
The lights are available from London furniture company Chest of Drawers, who happen to work at Dezeen's offices.
