Based on the traditional Nordic ‘kuksa’ cup, these eco-friendly long handled cups are composed of a proprietary natural fiber composite: cellulose fiber from managed Finnish forests reinforced with FDA approved food-safe polypropylene. The long lasting material yields excellent properties, including thermal insulation (to keep contents hot), exceptional durability, and the ability to age gracefully—much like pure wood. Use them as camp cups for coffee, hot cocoa, or soup. Dishwasher safe.
