I've got several TWISBIs and have to say that I like this cheap little pen just as much as it more expensive cousins. I like to fill my pens with colored ink for doodling and the TWISBI 1.1 stub is one of my preferred nibs for that purpose
Got a medium nib for this TWSBI. It feels lovely (although I wish I would have chosen a broad nib), the system to fill the pen with ink works perfectly and the capacity is huge. It glides across paper!
This pen is easy to use, straightforward to fill, and looks pretty cool! It feels very nice in the hand, writes great, and I love to see the ink sloshing around inside the barrel. I’m so glad I got it!
