Ultem Pen Spare Parts
These sections allow you to use your Smoltem (Pocket Ultem), Full Sized fountain Pen (Aluminum) and engineered plastics pens with other writing tips/nibs.
Right now we have Ultem 8 (Bock 380) sized sections , #6 Jowo Sections and ballpoint/felt tip sections**. These fit into the Ultem Full Sized Pen and not the Pocket 6 Pen.
Here is a comparison photo of the V1 380 grip vs the V2. It is .2" longer ! 
Another photo showing a 380 nib seated in the grip. (Note, the nib tip distance is the same length from the pen. So the nib is not deeper inside the grip)
**The Ballpoint/felt Tips sections are full the full sized Engineered Plastics and Full Sized Aluminum Pens and will not fit the Smoltem (but the rollerball tips will fit!).
This does not come with a nib! BYON (bring your own nib)
The ballpoint/felt tip refills can be purchased here as well and do not come with the grip
