The February 2010 issue of Monocle featured a little blurb on the work of Sosuke Nakabo. One of the pieces he designed recently is this witty collection inspired by stationery. They look like stacks of paper and post-its, but they are actually storage boxes!
Designboom has more pics of these when they were shown at last year’s Tokyo Design week. Not sure if these were just conceptul or if they are actually going in production, but they are really fun nonetheless. More here. (images by and via Designboom)
