The sushi rice ball machine on the market has a small leakage pocket? Do you need to refill the rice several times to operate the machine, which is a waste of labor? Ono Hisada's sushi rice ball maker has an enlarged funnel, which can put in 3~4 pounds of rice at a time, and can produce more than one hundred rice balls at a time to meet the high demand during peak hours and greatly reduce labor costs.
