TWSBI Vacuum 700 Mini Fountain Pen, Smoke, Medium Nib, TW100207

A simple guide to choosing a nib size in the incredibly complex world of fountain pens: If you write small, you can write with EF. For regular writers, F is the most popular. If you tend to rely on larger fonts, M is perfect. Write your signature with B, write headers with B, and color/shade with B. Stub nibs are italic (do you have a special card or invitation?) Vacuum-fillable fountain pen. Pocket-sized. Simply unscrew the end cap, pull up, and push down. It's filled with ink. The cap rests on the back of the pen. Available in EF, F, M, and B nib sizes.
