Thank you for viewing. This is a work by the artist. The ring and ring case were obtained as prototypes. The ring case is made of paper and cannot be opened or closed. The ring can be taken out of the case, but it is very small and delicate, so it is recommended to display it in the case. Please understand the above before purchasing, as this is not a product that was sold as merchandise. It has been stored in a dark place, but I am selling it to organize my collection. No individual sales.
