I'd never heard of TWSBI until I bought this Diamond 580 from Wonder Pens in Toronto. It's a demonstrator (filled with ink here) and I can never resist a clear pen, so I took the plunge.
It's made in Taiwan, by a company that previously made pens for other firms but has started putting out pens under its own name. It was $50 and for that, it's a really nice pen. It has good heft, the piston works smoothly, and it writes very nicely. Their website shows a number of other items, including ink bottles and journals, and I'm looking forward to trying some of their other products in the future.
