Thread: Uninformed question on Jnats

Maruoyama stamps their stones on the side, if there's space, so that's nice, but otherwise the stamps aren't nearly as important as the person you buy the stone from. This is every bit as true in Japan as elsewhere.

The difference is, Nakaoka uses dollar store ink. Old_School was selling vintage stones, I think, so they were stamped by guys who were marking stones for the general market--meaning they had to resist handling, and even some testing.
