These lacquered bowls show off amazing lathe work. They have a lacquered interior. They were cleaned with turpentine, then treated with a Monkey Wax polish and given 3 weeks to cure. They were part of this cohort if you want to see before/after.
The bowls measure 12.6cm wide and 8.5cm tall. They could be Nara (oak) or Kuri (chestnut) based on the brown tone, but the evenness of the grain lines makes me think they are old Kuwa (mulberry) or Keyaki (zelkova). The bottoms and insides are lacquered, as are the undersides of the lids. The lathe-work is amazing, creating perfectly symmetrical grooves from top to bottom, even on the lids. This is especially notable because of how thin the sides of the bowls are. A few hairline cracks were treated with wood glue.
The white stones are Japanese clams, which are slow-growing and therefore have incredibly dense lines. They are not as white as Mexican clams, but the lines of Japanese shell are beyond Snow-grade. The black pieces are slate. There are are 180 of each color, plus 5 white spares in case any are damaged in shipping. The white measure 4.8-5.1mm, and the black measure about 5.5mm thick.
