Ercolessi (Italy) - See E.E. Ercolessi -

The Ercolessi Company was founded in 1921 in Milan by two people named Edgardo and Elvira, from whose surname the name originated, and was dedicated to the trade of high-quality writing instruments.

Edgardo Ercolessi was a good friend of Armando Simoni.

In 1996, with the idea of paying tribute to that establishment, Omas manufactured a pen for that brand.
