Japanese graphic designer Naoko Kimura was inspired by the vibrant colors of vegetables and created the Oyasai Crayon, which makes the most of vegetable waste and by-products of the rice production process. The edible crayons are made from solid rice bran wax and liquid rice brain oil, which are used to polish rice, and colored with fruit and vegetable powders. Each crayon is named after the fruit or vegetable that matches its pigment—Carrot or Purple Potato, for example.
The food-based, waste-reducing crayons are now available in Japan and they are being introduced on Kickstarter to expand their reach globally. The vibrantly colored crayons inspire appreciation for the natural world with bright shades of green, red, purple, orange and yellow.
