Leonardt EF Principal Nib
This is a new nib from Leonardt and is closely based on the Principality No.1 vintage nib, which is now very rare. The Leonardt EF Principal produces excellent shades and crisp hairlines. This is the perfect nib for Spencerian and Copperplate writing.
Can be used with any pen holder that has a ‘universal’ ferrule. Also, all the Oblique holders with a metal flange.
