※Please be sure to read the profile before purchasing※ This item is new and unused. I bought it for my child, but they said they wanted a different size, so I'm selling it. This is a 450ml plastic lunch box featuring "Chikawa." It's designed to prevent decorations from being crushed and to keep nori (seaweed) from sticking to the lid, allowing for "fluffy" arrangements. Since this is an unopened product, please contact the manufacturer for any defects. ■ Size: Approximately 17.0 x 10.5 x 6.0 cm ■ Capacity: 450ml ■ Body weight: Approximately 150g ■ Microwave-safe (remove the lid) ■ Dishwasher-safe (for home use) ■ Includes a high divider to prevent side dishes from shifting ■ Securely sealed with a packing and fastener ■ Antibacterial with silver ions (AG+) ■ Made in Japan Although the product is new and unused, please refrain from purchasing if you are overly concerned about minor details. It will be shipped via regular mail, so it will not be wrapped in bubble wrap or similar packaging. If you prefer anonymous shipping, it will be an additional 500 yen, so please comment before purchasing.
