The idea behind the TWSBI Diamond 580 Clear fountain pen was to go back to basics and capture the simplicity and elegance of traditional writing instruments. The Diamond 580 is a classically styled fountain pen with a piston ink-filling system, smooth-writing steel nib and a screw-on cap. The traditional mechanism of the fountain pen, combined with a modern industrial design, embodies both the past and the present.
The TWSBI Diamond 580 piston ink-filling system uses only bottled ink and the clear body allows the user to view the level of ink remaining in the pen at all times. The Diamond 580 fountain pen has all detachable parts, as TWSBI felt that it was important to allow the user to disassemble and reassemble the pen to completely experience the traditional aspects of owning and using a fountain pen.
"Great service and a nice personal touch. I'll go back to them.

Great writer, holds a lot of ink!
"Just a quick note to sing the praises of the TWSBI 530 I bought from you at the Atlanta Pen Show in April. I filled it with MB Burgundy Red on April 13. I have written extensively with it, although probably not as much as others in my rotation. However, I noticed that it continued to have lots and lots of ink. I wrote more and decided to see just how far I could go, writing with it at the same level of use as before. Today, I felt guilty and decided to do some cleaning. The reservoir still had about 1/8"" of ink left. I bought the F point. Perhaps that is uses less ink than the M. I keep travel journals.
As impressed as I was with that, I was even more pleased when clean-up time came. This pen has to be one of the easiest and quickest pens to maintain. A few flushes and now it's soaking a bit. However, it looks clean as a whistle.
I neglected to say upfront what a great writer it is. The balance, grip and handling fit me perfectly."

LOVE MY NEW TWSBI Diamond 580, clear EF
This pen is everything the marketing promised. It is well made, balanced and functions perfectly. Top it off with stunning good looks and you have a writing tool that would be a good value at twice the price.
I have relatively small hands and prefer to write without posting the cap of my pens, so this pen is a terrific fit for me. I believe the nib is a Jowo #5 steel EF, which is firm and fair, I may polish it a bit, but it is NOT overly toothy. The pen really is a blast to use. I love watching the ink slosh around in the chamber! I have already tested it in my various journals, Moleskines, Webbies, Quo Vadis, etc. and I am confident it will become a regular in my rotation of fountain pens.
Anderson Pens packed this pen (and my ink well and leather pen case) with extra loving care and exceeded my expectations with their super speedy shipping. I highly recommend this pen and the fine merchants of Anderson Pens.

Great pen ... very happy!!!
What can I say ... very surprised and happy with the pen.
Firstly - the look is cool. The clear 'demonstrator' look is great and enjoyable by itself.
Secondly - the feel is great. Fits nicely in the hand, good balance and the weight is nice (could be a tad heavier - but that is a personal opinion).
Lastly - the writing. This pen writes very good from the first time charged up with ink. The flow is good and is smooth to use. I was worried that the EF might be too fine - it wasn't. It works with my writing style perfectly - I can annotate in small writing within margins easily and yet write full pages with equal ease.
I can see this pen becoming a regular favorite of mine.
Give it a go - I think you will be as pleasantly surprised as me. :)
