This fountain pen is Stipula's Ventidue model, but made out of solid metal! The purple ink window allows you to see your ink level. This pen fills via piston mechanism, and utilizes a #6 steel nib. All Stipula fountain pens are handmade in Italy. This is a limited edition, numbered out of 351 pieces.
The metal is specially formulated with a heavy component of iron. "Tocco Ferro" is an Italian phrase that translates to "iron touch", which is an equivalent to the "knock on wood" expression, like a gesture of good luck.
