Edison Hakumin Urushi Mina with extra-fine nib. This is a custom urushi pen from Brian Gray at Edison Pens and Ernest Shin at Hakumin Urushi Kobo. I am very lucky.
The pen is just gorgeous. The finish is Ki-tamenuri, which has a brown finishing coat and a yellow under-layer, which is easiest to see on the section threads.
The wonderful nib was customized as well. Brian sent it off to Mike Masuyama to be ground extra-fine. I asked for the equivalent of a Sailor fine.
KWZ Maroon is the ink. Also wonderful.
