Choice: EF, F, M, B. Will fit the previous generation 540 and 530 fountain pens. Easy holder case for storage when not in use. Quick and Simple changes between nibs. No hassle. 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.
