Kiso Hinoki Cypress Height: 21.1 cm Width: 13.8 cm The back is dark brown and lacquered, with the artist's brand. The surface is painted with gofun (oyster shell powder) for authentic coloring. It is important to faithfully reproduce the scratches and stains on Noh masks, so the dirt and scratches are intentionally reproduced. There appears to be a scratch on the nose, but it was intentionally added because it was also present on the model Noh mask.
