This 500 Series Pen is made from brass with a titanium tip, end piece, striker and pocket clip.
The Matthew Martin 500 Series Pen is well-balanced and has a robust build. The pen features a fine thread pitch cap that can be threaded on the non-writing end as well. The reverse side has an effective point for striking and compliance techniques. Excellent writing is facilitated by a replaceable medium black Fisher Space Pen cartridge, and, if desired the pen will accept Parker style refills as well (sold separately).
