Kyuseido Gravitas Kakari Full Size Demonstrator/Titanium Fountain Pen
This pen is lovingly used and does have some minor scratches on the cap of the pen (see last 2 images). It comes complete with a box and papers and is equipped with a 14k Cursive Italic nib and fills via a piston filling system.

From Kyuseido:
As the first pen ever introduced by Kyuseido, the Kakari draws its inspiration from the brand’s fighting spirit and commitment to design and quality. “Kakari” is the name of a move from the ancient game of Go, usually played in the starting turns as a challenge to the other player. Kakari represents our first move in the stationery world and our indomitable spirit.
The titanium parts on this pen are finished with a machine brushed texture.
The Kyuseido Kakari FS is the result of a collaboration between Kyuseido and Ben Walsh Design (Gravitas Pens), showcasing the cutting-edge Pump Piston Filler integrated filling system. This pen stands out for its exceptional craftsmanship. The body is crafted from optical-grade cast acrylic, prized for its crystal-clear finish and stunning polish. Inside, a 303 stainless steel piston unit and rod drive the innovative Pump Piston Filler.
The cap, section, and piston knob are made from durable Ti-6Al-4V titanium and feature a high Ra finish, precision-machined on a Swiss lathe. Delrin® acetal homopolymer lines both the cap and piston knob, providing a smooth and seamless capping and uncapping experience.
The piston rod includes a valve system that seals off the ink chamber from the nib, reducing the risk of leakage during travel. For optimal ink flow, simply unscrew the piston knob to allow free movement of the piston rod before writing.
