The Pilot Custom Urushi fountain pen is made of Urushi lacquered ebonite and is an oversize fountain pen with the largest size of any Pilot fountain pen. It comes with a large #30 size two-tone 18k gold nib. Made with Maki-e technique using Urushi lacquer, the body of the Pilot Custom Urushi glistens beautifully due to the use of the Ro-iro finishing technique, which requires repeated application of layers of Urushi followed by polishing and a final polish performed with the bare hand to ensure a mirror-like finish. While its Urushi lacquer gives this pen everlasting durability, its ebonite material allows it to remain light and comfortable to hold even while being an oversize fountain pen.
