This vintage Paper Mate Rocephin Injection pen is a rare find for pharmaceutical collectors. It is a new, unused item advertising for drug that was designed to be used once a day to administer the Rocephin Injection. The pen features the Roche logo and is a unique piece of medical history. Each of these pens are brand new in original plastic and were stored for many years. The drug insert says revised in September 2000 and it was printed in USA. The country of manufacture is unknown, adding to its intrigue. I decided to open and keep one pen for myself and it works / writes fine, just like any other paper mate does. This collectible item falls under the Science & Medicine (1930-Now) category and would make a great addition to any collection.
