Kamoshika Dōguten Suribachi (Grinding Bowl) Despite having no grooves, this bowl grinds ingredients effectively. Because it lacks grooves, it's very easy to wash. And because there are no grooves, you can mix freshly ground ingredients with vegetables directly in the bowl and serve it at the table. It's a great item that can be used both as a suribachi and as tableware. I've only used it a few times, so it's in very good condition.
