Set of 3 lunch boxes. Not sold separately. Compared to aluminum lunch boxes, plastic lunch boxes are less likely to have rice grains stick to them, making them easier for children to eat. I was told this by the principal of the nursery school, and I obtained these plastic lunch boxes, looking for ones that could be opened easily. The Hello Kitty and Sugar Bunnies ones are rare items. If you are interested, please consider purchasing them soon. They were used at a nursery school, so there are some scratches, but they can still be used. Please understand that these are used items before purchasing. They will be packed in a plastic bag. Anonymous delivery, Mercari delivery.
