Fitted with our world famous #6 FPR extra fine tipped ultra flex nibs, these nib units are compatible with pens that take #6 JoWo nib units, including the FPR Tanoshii.  They write with an extra fine 0.4mm line on the thin end and 2.0mm fully flexed.  They are tipped with top quality German made material for a smooth writing experience and are manually adjusted to produce a softer and more enjoyable flex experience.

(Note: These units do not have JoWo nibs.  They are fitted with FPR nibs inside a housing that is threaded to fit pens that take #6 JoWo nib units.)

Features:

• Feed material: Plastic
• Compatible pens: FPR Tanoshii and any other pen that accepts #6 JoWo nib units.
