This fountain pen is aesthetic: smooth, clean, with nice shapes. The pen is soft and gentle, regular ink flow. The line thickness is intense and corresponds to European fine. The fountain pen is a good size for better ergonomics and accepts short and long standard cartridges. This, unlike Cocoon and Metropolitan models that only work with Pilot cartridges and converters. Unfortunately, Mr is a bit too heavy for me: about 23 g in total, including 14 for the body and the pen. Too bad this is unacceptable to me.
