TWSBI Vac 700 Nib Swapping - Knox and Nemosine Nibs

After the unfortunately failed attempt at swapping a Knox K35 1.1 stub into a Nemosine Singularity, I got the idea to try the nib in my TWSBI Vac 700. Truly, there was nothing to lose, since buying a TWSBI 1.1 stub would have been an extra investment, and I had been interested in trying a stub with the Vac 700. Unfortunately, the same issue, as had occurred in trying to use the Knox nib with the Nemosine Singularity, once again reared its head, and the trial of the Knox nib in the Vac 700 was over. However, this lead to an idea: If the Nemosine Singularity and the TWSBI Vac 700 both had the same issue with using the Knox nib, would their own nibs be interchangeable? After some more experimenting, I present to you...

The TWSBI Vac 700 with Nemosine 0.8 stub nib!

And some writing samples!

While the Nemosine nibs may not be at the same quality level as the JoWo nibs used by TWSBI in their Vac 700, Nemosine does provide the options for a 0.6 and a 0.8 stub, which are not available for the Vac 700. Side note: I believe that the nib size number for the Nemosine nibs, the Knox K35 nibs, and the TWSBI Vac 700 JoWo nibs is #6. Now, if one of this companies would just make a double broad, life would be even better...

I hope you enjoyed this post. If you have any comments or questions, please feel free to post them!


  1. I'm really glad I found this post because recently I got a Vac700 with a 1,1 stub I wasn't happy about but I really didn't want to spend for a whole nib unit.
    Your experiment made me look around for non-TWSBI replacement nibs and now I can enjoy my pen more (and have a few spares to play with) :)

    1. I hope your spares are working for you! Which replacement nib has been your favorite, thus far?
