Bock nibs are high quality, distinctive nibs and provide opportunity to upgrade the standard fountain pen nib.

• Choose extra fine, fine, medium or broad.
• This nib unit comes with feeder and threaded housing as pictured.
• All nibs include the Bock housing and feeder system (unless we are changing the nib for you as part of your pen purchase).

Number 5 Nib

• Size 5 means the feeder is 5 mm in diameter, at the shoulders of the nib.
• This #5 nib fits the following fountain pen styles: Frankie, McKenzie, Urban, Classic, Vertex, The Boss, and Harold Junior.

If you are purchasing a pen from us we will change the nib out for you with our compliments.

 Upgrading your existing pen nib is easy to do yourself.  To change over the nib in a pen you have in your possession,  use the existing housing and feeder system from your pen. If you have difficulty changing your nib we can assist you over email or phone. Please contact us during standard work hours.
