Thank you for viewing. This is a fragment of Jomon pottery that I purchased (or received) a long time ago from a history museum (or experience facility). It was sold as a genuine piece of pottery. Due to long-term storage, there are minor scratches and dirt, but it is in the same condition as when it was purchased. *Please note that I have not had it professionally authenticated, so please understand that this is for "reference/display" purposes only.
