For and against

A sensible mid-catalogue piston filler that lives in the V126's shadow.

What owners say

P50 is my favourite. The grip on the #8 nib pens are too thick for me. I still use them though. r/fountainpens · 3 pts · thread
I don’t have either of these pens but I absolutely love my others (P20,P50, C80, V128) and I have both TWSBI ECO and 580 and love them both. It would be a different choice. The only thing I’d say is TWSBI nice you all the tools to clean your pen right in the package and I Had to order the cleaning kit from Amazon for the my 128s. r/fountainpens · 2 pts · thread
The black trim and black transparent resin makes for such a great look. I have the P50 in the same colorway and it’s also great, a piston filler. r/fountainpens · 2 pts · thread
I really would love it too if Asvine expanded their color choices. A Matte Black to match my V126 and P50 pens would be a no-brainer. I also hope they sell nib units as well. r/fountainpens · 2 pts · thread
Both surprisingly gorgeous- I’d love to see the writing samples and hear how they write? While I really like my Asvine P20&p50 and my absolute favorite is the J16 ebonite- I really don’t enjoy the V126 or the P80 - I’ve tried to enjoy writing with them but just can’t seem to find the right ink - the nibs just don’t feel as smooth. I have 2 of each and both EF and F in both yet not a fan. r/fountainpens · 1 pts · thread
I love that black transparent/matte black trim combo, I have it for the V126 and v200 and when they introduced it for the P50 I got it immediately. r/fountainpens · 1 pts · thread
