TWSBI ECO Fountain Pen – Cosmos Blue w/ Onyx

Specially designed for beginners exploring the world of fountain pens and equally loved by seasoned writers, the TWSBI ECO is a dependable everyday companion.

The TWSBI ECO (“economical”) offers the same high-quality, high-capacity piston-filling mechanism found in the TWSBI Diamond 580, but at a more accessible price. This Blue w/ Onyx edition features a striking transparent barrel paired with a bold onyx-black cap and accents, creating a clean and modern look. The hexagonal screw-on cap posts securely on the back of the pen for comfortable writing.

Each pen comes in a sleek clear case with a minimalist aesthetic, further protected by an outer cardboard box.

A quick no brainer guide in choosing nib sizes in an overly complicated fountain pen world:

• If you write small, go with an EF
• For the normal writer, F is the most popular
• If you tend to lean on a bigger font, M will be perfect
• B is for statements!! Sign a check in B, write a header in B, do some coloring/shading in B
• Stub nibs are italic in writing style (have a special card or invitation to write?)
