Anderson Pens own German-made #6 gold steel Extra Fine fountain pen replacement nib by JoWo can be used with any pen that has a #6 sized nib, including, but not limited to many Monteverde, Conklin, and Noodler's pens, as well as most others that accept standard modern #6 nibs.

Please note that our 1st version of these nibs were two-toned, but JoWo has since changed to single tone gold plated.
