Four Kol Mechanical Pencil
A Four Kol pencil with four different color lead - black, blue, red and green. There is lead of each color in the pencil and the mechanism works properly. It uses 2.0mm lead and a quick Google search shows this type of lead is available. I will include some extra lead. The pencil measures 5 7/16 inches and the eraser is in reasonable shape. I estimate the pencil was made in the 1950s, however, I could be wrong. A very interesting mechanical pencil!
