After purchase, it was kept in a plastic bag and stored on the bookshelf. I am selling it because I don't use it. I believe there are no noticeable stains, but please consider that it is a used item and has been stored at home for a long time. ❖ It will be reinforced with cardboard, etc., and will be sent by post. ❖ Packaging materials may be recycled. ❖ No pets, no smokers.
