Plenty of variations available of the Papermate Contour Pen. The Contour body style has been used on some of the most collectible Papermates ever made. This would include the Ops N Pops and the Zodiac. Zodiac has 12 different pens and the Ops N Pops has at least 10 different designs that can be on 5 different color pens. The 3 on the right side of the picture are made in the US but assembled in Mexico. These are somewhat different because of the white plastic tops. Most of the common Contours are the same color top and bottom. Same goes for the 2 Malibu's on the left. All of these are great pens from our past so add some to your collection.
