The Nu Spiral was a joint research project with Zebra Japan and Prof. Isamu from Waseda University of Japan. The pen was especially designed for comfort. The round grip has a triangular base structure, so its shape gives maximum comfort for your fingers. In addition, the unique spiral design of the body maximizes contact and allows the pen to rest naturally on your hand. Aesthetics are seamlessly blended with ergonomics to create a very well-balanced and comfortable multi-pen.
