1930s Pilot (Namiki) black urushi over hard rubber. The pen is in very good condition, but showing expected wear. The nib is a superbly flexible Fine marked Warranted Pilot 14 K Made in Japan #2. I was not at all sure how to price this, so I checked with my resident expert who advised $500-600. I have filled and used the pen. It holds ink and writes superbly, but would advise having it resealed before entrusting your prized kimono to it.
