The TWSBI Eco Fountain Pen is a piston-filling fountain pen that brings a satisfying, hands-on feel to everyday writing. With a built-in filling system right in the barrel, it holds an impressive 1.75 ml of ink—nearly double the capacity of a standard converter pen—so you can write longer and refill less. To fill it, just twist the knob, dip the nib, twist again, and you're ready to go. The cap posts securely and seals tightly to keep your ink fresh between uses.

Inside the carrying case, you'll find:

• TWSBI Eco Fountain Pen
• vial of silicone grease for lubricating the piston mechanism and feed threads
• plastic wrench to safely disassemble the pen's piston mechanism for deep cleaning and maintenance

Note that this pen does not come pre-loaded with ink. Ink must be purchased separately. 

Materials: acrylic resin, stainless steel
