Osprey Pens is proud to present the the first of its kind in the market - a rust proof stainless steel ferrule / nib insert, for dip pens and calligraphy straight holders. You no longer need to deal with the nickel plated and other nib inserts that tend to rust.

The Osprey Pens stainless steel (SS) ferrule is designed with the same dimensions as standard universal ferrules. It fits into any straight pen holder that takes standard universal ferrules. Osprey Acrylic and Ebonite dip holders come fitted with our new SS ferrule. This replacement unit is now available to fit your other penholders with a rust proof nib insert.
