- 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!

Very happy with the pen. It looks good, feels comfortable in the hand and writes well.

Writing experience is very pleasant. I love how the ink flows from nib. I like it how writable this fine nib is. It doesn't matter if pen is little bit tilted in one way or another and ink flows with gentle touch or even with little pressure. It is just solid nib.
I love how much ink I can get to the pen. Instead of switching cartridges (way too often) I can fill my pen and just write.
I've had earlier three different LAMY pens and I were wondering if this pen is too thick or heavy. My fears went away as soon as I started writing. This pen feels good in my hand. My hands are medium sized for a man. Size 9-10 glove.
I filled the pen with Pilot Iroshizuku ink if you are wondering the brand of the ink and you want to compare against something you know. It flows well and looks good.
This is my first pen with screw on cap. The cap feels just right. I've kept the pen in my backpack (upright in a pocket). I've also carried the pen in my cargo pants and the pen didn't leak... even inside the cap.
I've used TWSBI Diamond 580 so often, like two days without usage tops... so I can't say if ink dries slow or fast under the cap. Some people advertised that ink doesn't dry up in TWSBI pens. Time will tell.
All in all, I am very happy for my purchase. This was money well spent.
