The Japanese design team Yuruliku, comprised of Bananao and Kinue Oneda, focuses its energy into stationary creations, and now they’ve developed what they call the Green Marker. They are Post-it notes shaped like blades of grass and meant to be used as bookmarks. The more you read, the more lush your lawn becomes…and your mind, for that matter. For about $8 (735 Yen) you get 75 blades, just remember it isn’t necessary to hose them down every morning. Your first edition of Catch 22 wouldn’t like that very much. You can get them from Yuruliku’s online shop, or various stores throughout Tokyo if you happen to be in the area.
