This special collection was introduced in 2019 and is unique for many reasons. The Miya design and material was introduced in the late 1990's and was a staple in the Montegrappa line for many years. As new models were introduced the Miya was phased out and was no longer available.
Kenro industries decided to bring it back with the remaining parts in Montegrappa's factory. Kenro named the collection Miya 450, because there were only 450 fountain pens available to create the collection.
