Wooden Bowl Kneading Bowl 51cm Carved Kneading Bowl for Noodles and Soba Making Extremely Thick, Shallow Interior. Approximately 8cm deep at the deepest point, measured by an amateur. It's heavy, weighing about 8kg, and the wide base provides stability even when applying force, so I think it can be used hard. I think it's probably unused, but it's been stored at home. Please check the images before purchasing.
