TWSBI ECO Black Marble with Bronze Fountain Pen
TWSBI ECO Fountain Pen – Black Marble w/ Bronze
Specially designed for beginners discovering fountain pens and equally appreciated by experienced writers, the TWSBI ECO Black Marble w/ Bronze is a reliable choice for everyday writing.
The TWSBI ECO (“economical”) features the same high-quality, high-capacity piston-filling mechanism found in the TWSBI Diamond 580, offered at a more accessible price point. This Black Marble w/ Bronze edition showcases a beautifully marbled black barrel accented with warm bronze trim, creating a refined balance of classic and modern style. The hexagonal screw-on cap posts securely on the back of the pen for comfortable and stable writing.
Each pen is presented in a clear, minimalist plastic case and further protected by an outer cardboard box—ideal for storage or gifting.
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?)
