The first time I encountered the Mozart was by accident, I bought a Montblanc Meisterstück expecting a normal sized 144 but the pen I got was significanlty smaller. The Mozart is technically the Montblanc Meisterstück 116 and apart from the smaller size it has threading on the barrel to make screwing the cap on at the back possible. When the cap is screwed on it has a nice heft and is actually very nice to use, but it is great to stick somewhere in a purse or to attach to a notebook. It can be considered a pen for ladies, but I would also recommend it for men with smaller hands or people that like to have things compact.
