Oddly enough the cap and section threads on the Namisu and Ensso are the same. The cap from the Ensso will thread to the Namisu but the cap diameter is a little smaller. The Ensso section will thread to the Namisu as well but the converter hits the end of the body leaving a very small gap section to body. The Ensso section only works with the Ensso cap due to the larger diameter near the nib. Kind of interesting.
Anyway, lets see some titanium pens! Love this material!
