Long-term storage. I don't know what category it falls into. There are no noticeable stains, but the wooden shoes look sun-faded. There might be a smell. I am careful about future storage, but there is a smoker in my home. If you are concerned about details regarding the product, packaging, or shipping, please refrain from purchasing. I may delete the listing suddenly. I will pack it as compactly as possible. I may change the shipping method between Kuroneko Yamato and Japan Post.
