While looking for a mere flexible plastic cutting board suitable for backpacking, I discovered Orikaso plastic-oragami campware. Made of flexible and durable plastic, pre-scored for folding with small plastic snaps, this proved to be a very useful, light, affordable and cool tool. It serves as cutting board, plate, bowl, pasta strainer, melitta-style coffee maker, and funnel. After three weeks of daily use in Iceland it’ll never leave my kit again.
