TWSBI Diamond 580

I tried a FPR 5.5 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.

TWBI 580 Diamond. I think people like them so much is because of the ink capacity, the weight and the overall quality of the pen. It’s nice and long and heavy (at least in comparison to the other pens I have) and holds a ton of ink.

I got 4 new pens, the 9 Mini Iroshizuku, and a galen leather 20 pen case. My mom decided to go overboard for the holidays. The pens I got were a monteverde Regatta, a twsbi Diamond 580AL in Prussian blue, a Twsbi eco clear EF (Only for Baystate Blue), and a Scriveiner. I'm not familiar with the last brand but it writes wonderfully.

Excellent choice! A Diamond 580 has been my daily pen for about 5 years and has been an absolute pleasure. TWSBI also has exemplary customer service.

Twsbi 580 1.1 Stub. Stub is smooth and wet as heck, plus cursive with a stub (if you write your cursive at an angle, and hold the stub along that angle) looks amazing. They include the only tool required to take it apart because they want you to be able to clean and maintain it, and the nibs are easily changed or modded (adjust flow, correct tune alignment, etc).
