Breather holes

Most of the nibs we offer in this store have the option for cutting a shape from the usual round breather holw.

We cut it by hand with a fret-saw, so it is normal some differences  from the shown pictures below.

Most of modern feeders do not take the air from the breather hole of the nib, so enlarging the hole will not affect the unit ink flow.

Other shapes are possible, contact us if you have an idea!
