TWSBI

TWSBI is a new name in the fountain pen world, but they have been making pens for other companies for years. They take customer feedback seriously and often run Facebook campaigns to decide on new colours of pen designs.


You'll notice a hint of science about TWSBI's range, with the majority of their writing instruments possessing a demonstrator element. This allows you to see in to the barrel and observe the inner workings of a fantastically durable Taiwanese fountain pen. People often ask us how it's pronounced - As we're Welsh, and W sounds like the English U, we go with TOUS-BEE. You, however, can pronounce it however you like!
