Getting started, many fountain pen enthusiasts prefer the convenience of using plug-and-play ink cartridges over the bottle-fill piston mechanism. Traditionally, TWSBI's pen lineup consisted only of piston-fill fountain pens. In 2021, the Taiwanese company introduced their first entry-level cartridge/converter-filling fountain pen in the TWSBI Swipe. The Swipe's injection-molded resin body has a clear ink window to see the remaining ink in either the cartridge or converter.
