TWSBI Diamond 580 (Smoke Rosegold)
TWSBI is a Taiwanese pen manufacturer and produces good quality pens compared to some of the cheaper mainland Chinese brands. Indeed, Wing Sung produce copycat versions of their pens: the Wing Sung 3008 is a copy of the Diamond 580 and the 3013 is a copy of the Vac700. This premium version of the 580 features a smoked cap and section and gold plated finish to all the metal work. Even the aluminium piston is gold anodised. Like all TWSBI pens, it has a quality German Jowo nib (broad in this instance). It is therefore both very attractive and a good writer.
