TWSBI Eco Fountain Pen – Clear

The TWSBI Eco Clear is fully transparent from cap to barrel, giving an unobstructed view of the piston filling mechanism and ink level at all times. The same high-capacity piston filler found on TWSBI's flagship Diamond 580 comes at a fraction of the price, making the Eco an ideal first fountain pen or a reliable daily writer.

A polished stainless steel nib is available in five sizes, and the threaded cap posts securely on the back of the pen for balanced writing. An inner cap keeps the nib sealed and ready to write even after weeks unused.
