Omas Bologna converter/cartridge fillers in colorful acrylic material are part of the late Omas products. These pens were meant to be fast sellers, perfectly suitable for everyday use, light and easy to use.
Many colors were available. They were manufactured both as "doué" models with pearlescent blue/black caps and colorful barrels and as fully colored pens.
This Bologna is a doué version with pearlescent blue cap and orange/black barrel.
It is new old stock but it has no box.
