You will get six never used Iridinoid 777 EF nibs in perfect condition.
E. S. Perry Ltd was an English pen manufacturer established in the early twentieth century by Edmund Perry. Based in London, with a factory in Gosport, the company produced the Iridinoid range of dip pen nibs and later became known for its Osmiroid fountain pens and nibs. Surviving examples reflect the variety of designs offered for handwriting and lettering.
The Iridinoid 777 EF is a vintage English stainless steel dip pen nib with a rounded writing tip. It produces a very fine line, approximately 0.2 mm wide, and is not flexible.
