Unused. I've been storing this for a long time, but I'm putting it up for sale to declutter. With a cute Kumamon design, it can be used by a wide range of people, from babies for warm water to adults for accompanying their lunch. Although the outer box shows some scratches and deterioration due to being stored at home for several years, there are no scratches on the main body. Due to shipping costs, I will take the item out of the box and package it with protection. The box will be folded and included. Thank you for your understanding.
