The Pentel mechanical pencil has a modern, yellow coating that is comfortable to hold. The ridges provide an extra grip, so you can use the mechanical pencil for a long time. It feels like a pen, but creates lines like a pencil. The thin pencil refill creates neat, clean lines; ideal for sketching or writing. The metal push button makes it easy to retract the tip. That way it won't break easily. Under the push button you will also find an eraser. This mechanical pencil is suitable for 0.9mm refills.
