For making sushi at home, soba, and more. Set of 10 pieces - Material: Bamboo It can be used for rolling sushi, and I think it would look nice placed on a plate for guests. You can also use it with a steamer for mochi. - Size: 15.5cm x 7.5cm Although it is unused, there are some slight stains, which may be due to the material. I have priced it at this amount because I would like you to care for it at home. Please purchase only if you understand this. Thank you for looking.
