- EF particularly fine
The TWSBI Diamond 580 matches superior craftsmanship with distinctive design, creating a writing instrument every pen aficionado will covet. The striking diamond faceted barrel prevents your pen from rolling off the table, whilst the transparent construction allows you to see the piston fill workings and remaining ink levels. Sitting comfortably in the hand, this durable, lightweight fountain pen is finished with a screw-close cap and rubber O-ring to prevent leaks and drying. Match the Diamond 580 with the TWSBI Diamond Ink Bottle for an easy, fuss free filling experience.
All TWSBI fountain pens can be disassembled for cleaning and maintenance. TWSBI includes the tools to do so, but recommend this is only carried out by experienced fountain pen users. This should only be carried out as part of long term servicing of the pen; it will not need to be done straight away. All disassembly is carried out at the owners risk!

What an amazing pen... this is my third fountain pen.. my first was a Lamy Al-Star and then a Pilot Lecoule... the Lamy is a great pen so I went for the Pilot... didn't enjoy the pilot and found another home for it... I invested in the Twsbi and OMG I am absolutely in LOVE with this pen!! As soon as I wrote with it, so smooth, like butter... I got the Fine nib but ordered separately a Medium nib.. I put in the medium nib right away and will probably just use this one... Also the fact that it holds so much ink is superb!! This is my #1 love :-)

The purchase process was very easy, and the pen is just fantastic (I already knew that because it's the second one of this model that I buy). The fine nib is not scratchy and allows for much detail.
