TWSBI Eco Persian Green Fountain pen

The TWSBI Eco (short for economic or economical) is now available in Persian Green. This bluish green color is named after the classic green color found in Persian pottery and fabrics. The color is inspired by the mineral malachite.

The Eco is the cheapest fountain pen that uses the piston filling mechanism. The pen has a transparent holder that shows the mechanism well. The transparent container also gives the TWSBI a different look, changing with the ink it is filled with. The faceted cap gives the TWSBI Eco a powerful appearance. The TWSBI logo sits proudly on top of the cap.

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

TWSBI fountain pens can be completely disassembled for cleaning and maintenance. Instructions and the necessary tools are supplied with every TWSBI fountain pen. Please note that the disassembly function is only intended for experienced users and is not necessary in 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 has decided to start selling under their own brand, TWSBI. The name TWSBI is composed of TWS and BI. TWS' is the reversed initials of the phrase 'San Wen Tong', translated Hall of the Three Cultures, and 'BI' literally means writing instrument.
