All but one set of these bowls are used and from Japan. They have all been cleaned and polished. The 100 series holds up to 5 mm stones -- The 200 series holds up to 7.5 mm stones -- The 300 series holds up to 10.5 mm stones. There is, however a slight variation from one bowl to another, so if you have a specific borderline case, ask first.
