Lumos pen and parts

I am really enjoying my Lumos pens and the ability to to switch nibs, caps , inks! Great pen … great ideal!

Indispensable Keep these in your Lumos kit.

These rings are what creates a seal when you open and close the pen. If your Lumos gets a bit wobbly, your reservoir seems dry or won’t quite close all the way, you will need to swap the o-ring out.
