Sugito Contrabass Bow No. 1000G German Style I used it for a total practice time of about 10-20 hours, but since I mainly played pizzicato, I think it has little wear and tear. I loosened the bow when storing it during periods of non-use. Since it hasn't been used for a long time, I think it's best to have the hair replaced. A case is also included. #bow #contrabass #woodbass #case
