What a novel idea for the snack table. Sushi is not only a very healthy snack, it is becoming ever more popular with children and making your own is an exciting challenge. Provide boiled, cooled sushi rice to which a little bit of sushi vinegar has been added and then show your little ones how to roll their own with little sheets of pre-cut nori seaweed and some strips of cucumber. Made from Bamboo. Dimensions (cm): 14 (w) x 18 (l) for Mat. 5 (w) x 15 (l) for Rice Paddle
