This is a set of Kuroki sanba (clackers) from [Maedado]. There is no box. Made of Kuroki (ebony), these sanba produce a beautiful, resonant sound. They are a traditional Japanese instrument used in Okinawan (Ryukyu) folk music. Kuroki itself is becoming scarce, making these rare. Please consider purchasing them at this opportunity. Please understand that these are used and have been stored at home before purchasing. Thank you for looking!
