Thank you for viewing. This is a ring-shaped pendant necklace. The material of the ring part is unknown. It does not react to magnets. The chain part is stainless steel. Due to its properties, it reacts slightly to magnets. Please be aware if you have metal allergies. Chain length: approximately 48cm Please understand that there may be some slight variations. The color may differ between the photo and the actual product. Please be careful to avoid issues such as different sizes or a different impression than expected. I am not negotiating prices. Shipping is planned via Yu-Packet Post Mini, but the shipping method may change. Old newspapers, plastic bags, and waste materials may be used as cushioning materials. Please do not mistake them for trash. Thank you.
