This piston-fill fountain pen pairs a clear demonstrator barrel with Nickel Gray aluminum trim, so the ink and the mechanism inside stay on view as you write. The grip and cap carry a matte finish with fine circular engravings for a secure hold, and the whole pen comes apart into its separate parts for cleaning or a nib swap.
The fine nib lays down a controlled line, and the piston fill holds a generous reserve of ink, enough to carry you through long stretches of writing before a refill is needed.
TWSBI is a Taiwanese pen maker, and this design reflects that background directly: after 50 plus years as an OEM manufacturer for different global brands, Ta Shin Precision decided to start selling under their own brand, and thus TWSBI was born on 2009 in Taiwan.
