Set Contents: O-rin (bell) x 1 Rin-bo (bell stick) x 1 Rin-futon (bell cushion) x 1 Rin-dai (bell stand) x 1 Size: O-rin: Approximately 90mm diameter x 35mm height Rin-bo: Approximately 140mm Rin-futon: Approximately 85mm diameter Rin-dai: Approximately 85mm diameter Material: O-rin: Brass Rin-bo: Wood Rin-dai: PC (Polycarbonate) This item was stored unused after purchase, as I was already using an existing o-rin. Due to long-term storage, there are some stains on the inside of the o-rin (sorry, they are difficult to see in the photos), but there are no issues with the sound quality. It resonates with a beautiful sound. Please consider purchasing if you understand that this item has been stored at home for a long period.
