We are taking about 1957 to 1970. They had gold plated pens with diamonds where the hearts on the pocket clip are but these pens in the picture are what most of us used. On the left is the Papermate button retractable with the plastic bottom half from about 1958. Next is the gold color retractable from about 1957. Then comes the 1959 Capri III, Good pen. Next is the Papermate 98 button retractable. Push down on the top and the point comes out. Little button above the pocket clip was pushed to retract the point. This pen was made from 1959 to 1970 with over 100 million sold. Another good pen. The small one is the Lady Capri made from 1957-1963. The next three are different types of the Contour to include the Ops N Pops. Followed by two of the Papermate Profiles. I have the thin and the middle size, missing the fat one. Over on the right is carded Malibu with the famous Piggy-Back refill. Most all the pens in this picture used this type of Papermate refill. The small Lady Capri used only 1/2 have the refill. I do not believe that this refill had more ink them a regular one but it made money for papermate. These pens were all your common ones. I am still missing a Papermate Holiday and a few others. I recommend you get them all. Good pens.
