The Scripto K780 is the most notable and popular of the Scripto pencils but there are others that you may want to add to your collection. All these pencils use the standard Scripto 1.1mm size lead except the P452 on the left. The P452 TOP-AD pencil is new to the supply room and uses 0.9mm lead. It gets it's name from the Ad just under the eraser. Next is a Scripto 4-47 pencil from the late 40s and early 50s. Many of these pencils were used for advertising and can be found on eBay. They are a very thin pencil. I have five of them in my collection. Next is a ME-1. A real good looking old Scripto pencil in blue. To it's right is a M800 model used for advertising followed by the pearl version of the M800. There are plenty of variations of these M800s with some being called MP-1s. Both these M800s appear to have never been used. Last is the Scripto Wordmaster and considered by many to be one of the best pencils ever made by Scripto. All these great pencils should be in your collection.
