IN 1948  Omas restyled its entire range of products choosing a modern and fashionable ogival design  to be flanked by the traditional facetted lines  which were rejuvenated, too.

All the new lines were fitted with a piston filling mechanism and were named Extra 55X

The Extra  556 was the standard size and it was available both as a cylindrical model with the suffix "S" and as a facetted model with the suffix "F". The 555 was the ladysize and 557 was the oversize and they were available in the facetted and cylindrical versions, too.

The 556 is actually work horse, suitable for long writing sessions. It is light in the hand with a comfortable grip.

This  556/S is in excellent condition and it is a fantastic writer. it is fitted with a very smooth flexible nib, frame F.
