TWSBI Eco Amazonite Fountain Pen

The TWSBI Eco (short for economical) Amazonite is the most affordable fountain pen that uses a piston filling mechanism. The resin TWSBI Eco fountain pen features a transparent barrel that allows the mechanism to be clearly visible. This clear body also gives the TWSBI a unique appearance, highlighting the ink it is filled with. The faceted cap gives the TWSBI Eco a bold and strong look, while the TWSBI logo completes the top of the cap.

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

TWSBI fountain pens can be fully disassembled for cleaning and maintenance. Instructions and the necessary tools are included with each TWSBI fountain pen. Please note: disassembly is intended for experienced users only and is not required for normal use. Disassembly is at your own risk!

With over 40 years of manufacturing history, including producing high-end pens for other brands, Ta Shin Precision decided to sell under their own brand, TWSBI. The name TWSBI is a combination of TWS and BI. "TWS" is the reversed acronym for "San Wen Tong," which translates to "Hall of Three Cultures," and "BI" literally means writing instrument.
