TWSBI's Eco fountain pen features a twist piston mechanism that lets you store your favorite inks directly inside the barrel, no cartridge necessary. Simply dip your pen into the ink bottle of your choice, twist the piston knob to draw the ink directly into the barrel, and start writing. It really is that easy.

TWISBI fountain pens feature clear barrels that allow you to keep track of how much ink you still have in the tank. Smooth to hold and easy in the hand, they're perfect for beginners as well as collectors—TWSBI calls it "a good everyday worker" and we agree! This fountain pen is fitted with a medium nib that offers a little feedback as you write, almost as if your pen is interacting directly with you. Last but not least: the matte orange resin cap and piston knob for an extra dash of heat.

Precision and personality, all at an affordable price point. You can't go wrong with TWSBI.

About TWSBI:

With 50 years of experience in pen making, Taiwanese manufacturer TWSBI is beloved for its high quality writing tools at affordable prices. Most of their pens are made with transparent barrels, allowing you to develop your own technique and understanding of a pen's particular inkflow.

TWSBI's name comes from the phrase "Hall of Three Cultures" or San Wen Tong in Chinese. The phrase San Wen Tong recalls the Hall of the Three Rare Treasures, created by Emperor Qianlong as a memorial to three great masterpieces of Chinese calligraphy, with the character Wen translating to "language and culture." When reversed, the initials of the phrase San Wen Tong transform into "TWS". The last letters "Bi" was added with its literal meaning of "writing instruments". The two segments come together to create TWSBI.

Their mission is to inspire and recapture the romanticism of art and literature…starting with the pen.
