I received this item new around June 2025, and it is unopened and unused. The condition is good, although the plastic bag has some wrinkles and dust on the tape. I think it could also be used as a lunch bag. Exterior dimensions (excluding the plastic bag): approximately 20.7 x 21.6 cm. I cannot provide the depth as it is unopened. Please refer to the photos for details on materials, etc. Price is not negotiable. It will be shipped via Nekoposu (a Japanese delivery service) in a plastic bag or cardboard box, depending on the item's size. Bubble wrap will not be included. Please read my profile to prevent any issues. Thank you for looking.
