The cap is smooth while the barrel is faceted. The gripping section, connector and screw of the TWSBI Diamond 580 AL R Navy BLue are all made of blue metal. The TWSBI logo is visible at the top of the cap.
The TWSBI Diamond 580 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.

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.
