This is a used item, but it can still be used, so I am offering it for sale. This is a picture frame that allows you to feel the warmth of wood. There are no noticeable large scratches or stains, but it is a vintage item. For those who understand, thank you. Please refrain from purchasing if you are overly concerned about details.
