TWSBI Vac 700R Clear Fountain pen

The TWSBI Vac 700 Clear is a large fountain pen that uses a vacuum filling mechanism. The (semi-)clear body gives the TWSBI a different look with the ink it is filled with. The TWSBI logo finish the top of the cap.

TWSBI's vacuum filling mechanism fills the entire barrel with ink (almost 2.5ml) with a single up and down stroke of the plunger. When screwed fully down, the mechanism seals near the nib, giving extra protection against leaking. For short use, the pen can be uncapped and is ready to write. To use the fountain pen for longer, unscrew the piston knob a few turns to let ink flow from the barrel to the nib, but don't pull it up!

The TWSBI Vac 700 Fountain pen has a polished stainless steel nib engraved with the TWSBI logo, available in several sizes.

TWSBI fountain pens can be entirely disassembled for the purposes of cleaning and servicing. Instructions and necessary tools are supplied with each TWSBI fountain pen. Please note that the disassembly feature is only there for experienced users and is not necessary for normal use. Disassembly is at your own risk!

With a history of more than 40 years of manufacturing, including producing high-end pens for other brands, Ta Shin Precision decided to start selling under their own brand, TWSBI. The name TWSBI is made up from TWS and BI. ‘TWS’ is the reversed initials of the phrase ‘San Wen Tong’, translated Hall of Three Cultures, and ‘BI’ literally means writing instrument.
