※ Only those who wish to purchase should bid. This item was found in my grandparents' jewelry box while cleaning out their house. I have not had it appraised, so I do not know the material or value, and I cannot guarantee the material. Please refer to the current photos when purchasing. I believe it is a magnetic necklace. It may be effective for stiff shoulders, etc. There are two necklaces. We will not accept claims based on appraisal results after purchase. To prevent trouble, we do not offer refunds or returns. Thank you for your understanding. Thank you for viewing.
