The Extra model was introduced by Omas in 1932 in a very wide range of colorful celluloids.

The model was available in three sizes both with a cylindrical and facetted design. The features of the model were the rich and elegant greek key cap band placed between two thin cap rings and a typical roller clip.

This Omas Extra is a facetted medium size in gray arco celluloid. 

The pen is in excellent condition with very limited signs of use. There is some minor brassing on the clip.

Its nib is grade EF,  very smooth and flexible.
