A cute Sumikko Gurashi designed lunch box and chopstick set. The lunch box has been used a few times for rice. Since there is no indication that it is microwave-safe, I don't think you can heat it up in the container. The chopstick case and chopsticks have been opened, but are unused. The chopsticks are about 16cm long! How about it for your child☆ - Brand: Sumikko Gurashi - Color: White/Yellow - Material: Plastic - Included items: Chopsticks - Design: Character pattern - Size: Approximately 14cm x 8cm x 5.5cm (lunch box) Thank you for looking.
