For and against
- Piston filler at a cartridge-pen price
- Reported to hold ink for weeks without hard starts

What owners say
I love me an Asvine appreciation post! Congrats on the triplets! (I’ve got the V126 in frosted clear, like you, as well as a P20 and C80. They’re such great pens.) r/fountainpens · 12 pts · thread
I got an Asvine P20 last night and looks almost as good as a Leonardo (my favourite middle brand) r/fountainpens · 8 pts · thread
Do you like a heavier vac filler or a lighter piston filler? That's literally what it comes down to Quite frankly, the P30 has ended up being my favorite Asvine. The shape, styling and feel are awesome. The P20 is a looker. I haven't seen a photo yet that does it justice but it comes in 3rd for the feel category for me. r/fountainpens · 5 pts · thread
They are great nibs (especially for the price). I use one in my Asvine P20 and am happy with it. But from what I’ve heard, the gold one may be a bit stiffer than the silver one. There have been many posts about these nibs on this subreddit already, so I would recommend using the search function here to find people’s experience reports. r/fountainpens · 4 pts · thread
I love mine! It works great and writes great. Unfortunately the Asvine P20 has a serious flaw. Don’t recommend that one. r/fountainpens · 3 pts · thread

Very smooth, good ink flow. This is one of my favourite pens in my collection. r/fountainpens · 3 pts · thread
