The Blue Hour line, inspired by the light of billboards and vehicles glowing in the evening light of big cities, has always been a favorite of Montblanc collectors. The lacquer blue with small hexagons skillfully created by artisans, hidden under the lacquer, contrasts with the light and creates a wonderful pen model.
The pen you see in the picture is the highest-end version of the Solitaire Blue Hour line, a medium-sized version that fits almost all users. The pen is available in stores in brand new condition.
