Have you ever wondered what the M in front of your beloved M800 stands for? Do you have a DEF nib on an old Ibis and think to yourself what does that D stand for? Read on for a quick breakdown of what Pelikan’s letter designations stand for as gathered from various sources. Of course, I strived to make sure the following list is as factual as possible but there is always room for error, especially since I have no understanding of the German language. If you do see an error, please feel free to let me know so that I can make the appropriate correction. Many of these terms can also be found in the glossary.
