TWSBI ECO Transparent Blue
The TWSBI ECO is a piston filling fountain pen. This means that you simply unscrew the endcap, dip the nib into a bottle of ink, screw the endcap back in and you are ready to write! The ECO holds a significant amount of ink so you are able to continue to write for long periods of time. Also, because the body of the pen is a sturdy, clear acrylic, you are able to see the ink slosh back and forth inside of the pen as you write - something that is very enjoyable. The ECO is a budget-friendly pen that has proven to be a winner for both beginners and collectors alike.
TWSBI’s newest iteration of the ECO, this time in transparent blue!
