On the left we have two Papermate 4-Ball Pens. The blue one is your standard red, green, blue and black while the green one has the four neon colors. I have never seen these here in the US. Plastic bodies with rubber grips. Will have to open one up and try it. On the right are two 70s or early 80s Papermate Contours. The red one is a standard contour while the yellow and black one is the much harder to find Rally model. This makes my second Rally. Add them all to your collection.
