This is a tool used for repairing dents in various wind instruments. The diameter of the ball part is approximately 15 mm, the diameter of the rod part is approximately 9 mm, and the length is approximately 45 cm. This is a prototype created as a sample, so the price is slightly lower. Since it does not fit in a Letter Pack, it will be shipped via Yamato Transport's Takkyubin cash-on-delivery service.
