TWSBI Diamond 580 Fountain Pen
Great pen. Writes well. Smooth. Great quality.
This thing is solidly built, and holds a ton of ink. It's well made, and supports easily replaceable tips. I bought another one immediately.
Thank you for your consultative approach to helping guide my pen and paper purchases.
This is my 4th TWSBI. I love them all..but the Diamond 580’s are my favorite. I have the 580s in medium and 1.1 stub, which I prefer for most writing. Medium for other times.
