This is an upgarde rollerball with superb Rhoidium plated fittings and handmade by Sigma from Ebonite.

This is one of 2 styles of rubber pen-making material from the 1930's and it was obtained in rod form from a now defunct french pen manufacturer.

It really is special and it has been polished to perfection.

The pen takes a standard refill and comes in a Sigma presentation case with full Warranty.
