TWSBI Diamond 580ALR Nickel Gray Fountain Extra Fine Nib Pen,

The popular 580AL now features even more detailed grip and cap (matte finish). This is a piston-filler type fountain pen. It's easy to fill by simply twisting it, making it hassle-free. The 580 features improved smoothness in cap thread rotation. The 580 has increased ink capacity, which is about 30% more than the 530. Pen nib sizes available: EF, F, M, B, and Stub 1.1. Please see other listings for other sizes. A quick no-brainer's guide to choosing nib size in the overly complex world of fountain pens: For smaller fonts, go with EF. For regular writers, F is the most popular. If you tend to lean towards larger fonts, M will be perfect. B is for statements!! Sign with a B, write your headers with a B. The coloring/shading of the B stub nib italics to your writing style (do you have special cards or invitations?)
