I purchased this item as unused and stored it at home. Although I bought it as unused, it is an old product, and I am not sure about the storage condition, so please understand that. A matching placemat (unused) is included as a bonus, but it has stains due to long-term storage. I will use it for packaging; please let me know in the comments if you don't need it. There are marks on the back from the firing process; these are not scratches.
