TWSBI Eco Irish Green fountain pen

The TWSBI Eco (short for Economic) is now available in Irish Green with Onyx. The Irish green cap and piston knob are complemented by black metal details.

The Eco is the cheapest fountain pen that uses a piston filling mechanism. The pen has a transparent body that clearly shows the mechanism. The clear body also gives the TWSBI a different look, which changes with the ink it is filled with. The faceted cap gives the TWSBI Eco a strong appearance. The TWSBI logo proudly sits at the top of the cap.

The TWSBI Eco fountain pen features a polished stainless steel nib engraved with the TWSBI logo, available in various sizes.

TWSBI fountain pens can be completely disassembled for cleaning and maintenance. Instructions and the necessary tools are provided with each TWSBI fountain pen. Note: the disassembly option is only for experienced users and is not necessary for daily use. Disassembly is at your own risk!

With a history of over 40 years in production, including the manufacturing of high-end pens for other brands, Ta Shin Precision has decided to sell under their own brand, TWSBI. The name TWSBI is composed of TWS and BI. TWS' are the reversed initials of the phrase 'San Wen Tong', translated Hall of Three Cultures, and 'BI' literally means writing instrument.
