The TWSBI Eco (short for "economic") is the cheapest fountain pen that uses the piston filling system. The resin TWSBI Eco fountain pen has a transparent barrel which makes the mechanism to fill it up with ink clearly visible. It gives the fountain pen a special character depending on the ink colour with which it is filled. The faceted cap of the TWSBI Eco gives the pen a powerful look. Choose your colour and nib size by selecting the desired combination of color and nib size (in brackets behind the color).
