Twsbi Eco Indigo Blue Bronze Fountain Pen

TWSBI Eco Fountain Pen – Indigo Blue Bronze
The Eco Indigo Blue Bronze pairs a deep indigo blue demonstrator barrel with warm Bronze plated trim across the clip, cap band, and piston knob — a striking, rich finish on TWSBI's best-selling piston filler. The demonstrator barrel still lets you keep an eye on the ink level and piston mechanism.
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.
