The Red Stipula Duetto is a pen that stands out due to its intense red color, but also, due to the unique curves integrated on its design.
The pen is made of a perlescent red resin with color ranging from deep red to a light pink. It has a large nib made of 18kt solid gold, and uses a cartridge/converter filling system. The Stipula Duetto pens have a screw cap, with the threads on the side of the barrel positioned near the nib's ring, and so in a position that will not intefere with your grip of the pen.
The Stipula Duetto is a very interesting design developed by the Florentine manufacturer.
