Purchased around 2000, a Pilot Dr. Grip 0.5 mechanical pencil in silver and green. It has a "shake to advance" feature, where shaking the pencil extends the lead. As you can see in the photo, there are some areas where the silver finish has worn off. It functions normally as a mechanical pencil. - Brand: Pilot - Model Name: Dr. Grip 0.5 - Color: Green/Silver - Type: Mechanical Pencil Thank you for your understanding. Thank you for looking.
