TWSBI Diamond 580 vs Moonman M2

Additionally, the ink capacity on the Kaweco has never been a problem for me, as it always got me through at least a whole day of college notes with the EF nib.

I filled it with Thornton's Red ink, in the customary manner of matching the pen to ink color, and it is just a wonder to behold. The clear acrylic is luminous and sets off the translucency of the deep red ink creating an almost magical effect. I also really like the solid acrylic caps on both ends. They capture and bend the light in ways that are delightful

The price for such a good fountain pen is unreal. Pens of similar writing quality made in Germany, Italy, or Japan cost 2 and 3 times as much.

This pen is well priced, a value, and more fun to write with than the Delike Alpha, Pilot Metropolitan, or Lamy Vista I bought for a similar price. This will likely be my go-to travel/daily carry pen for awhile.

5 ultraflex in TWSBI 580 and it just didn't work - the inkflow wasn't there. Every #6 nib I placed into PenBBS struggled to function (and taking out the feed each time was a literal pain I do not want to repeat again). I bought Lamy nibs by mistake and don't even want to start down the Lamy road, so I'm leaving those untouched. I still love all the pens I have, but for future purchases, I think I'll stick strictly to the pens that take #5 or #6 Jowo nibs without much of a struggle in the feed

Can not recommend you purchase. Maybe I happened to get a bad one, but I’m not going to try and return a pen that I’ve clearly filled with ink. Other reviewers seem happy, so it’s quite possible this is a fluke, but I was not happy with this purchase. If I were to do it over, I would look elsewhere and pick up another Hongdian, or something in that equivalent price range
