These replacement nibs and calligraphy nibs fit most of the modern Conway Stewart pens. They are supplied fitted into a black nib holder so you can simply unscrew the barrel of your pen and screw the new nib holder in. Some nib holders have nib rings so there is a drop down requesting whether your pen has silver, gold or no nib rings.
If your Conway Stewart model is not in the drop down list, please email us for information about the availability. These replacement nibs do not fit vintage Conway Stewart pens.
