The 556/F is a timeless classic as it offers simplicity, balance, elegance ad high quality writing. The model is very light in the hand and is fitted with an Extra Lucens nib which can be extremely flexible. These pens were offered in a variety of grades and with varying flexibility degrees but  generally very flexible F or EF nibs are most common. B nibs are extremely scarce.

This 556/F is in excellent condition with very limited signs of time and use. The nib is F , very flexible, responsive and really pleasant to use.
