The Kurakin line from Norimaki, a Japanese purveyor of eco-friendly bags, toys, and kitchen accessories that recently showed at NYIGF, uses leftover vegetables and fruits to dye their products. There are currently eleven different dye colors made from food items like adzuki beans, peanuts, coffee, wine, and blueberries.
The Kurakin line features kitchen accessories such as pot holders, oven mitts, and dish towels ($3-$18), handled baskets ($40-$60), Furoshiki bags ($60), and childrens' balls and blocks ($18). Currently, the bags are sold by The Loopy Mango in Brooklyn, but the other items will not be available in the States until the end of March.
