Thank you for viewing. This is a set of four Otsuka Takekan Gakki Shinobue Shishida Takekei flutes with six holes. It appears to be the same product as the one in photo 11, which is still sold today, but the specific scales are unknown. They were used for about 20 years, accompanying taiko drumming. There are scratches and stains, but they can still be used as instruments. ◆ Size Length: 37.5cm ◆ We have cleaned them as much as possible, but there are still some blackish areas because we don't have the proper tools to clean the inside of the flutes. Please consider this item with the understanding that it is old. If you have any questions, please feel free to comment ^⁠_⁠^
