Very beautiful, solid and can be posted and become a very large pen. The 18K M nib is with some good flex and nice flow of ink. The nib is not as smooth as Visconti and Montegrappa pens but provide more feedback to me, just like writing with 4B pencil. The pen can house a Bock 250 nib assembly without a problem. I shall return for more of the Ancora pens, stunning!
