This pack contains 1 piece of clear barrel NU Spiral mechanical pencil 0.5 mm fine tip. This crystal-like pencil will help you conquer all your project foes. This pencil was a joint research project with Zebra Japan and Prof. Isamu from Waseda University of Japan, and was especially designed for comfort. The round grip has a triangular base structure, so its ergonomic shape gives maximum ease for your fingers during long-term writing. 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 pencil. Includes eraser, which is found underneath the top cap.
