Please note: Pens which we described as being in "unknown working condition" are pens which have not been restored or opened. Most of them will need Sac/Seal/Diaphragm change, some might have other inner parts in need of replacing or even missing. Unfortunately we are unable to test those pens. 

We have described the nib sizes to the best of our knowledge, however, in vintage pens, there might be a deviation of 1 size.
