BG66 ULTIMAX roll of string. I am selling this because I don't plan to use it. I measured it and there are 54m remaining, so I think it can be strung 5-6 times (6 times if used sparingly). - Model Name: BG66 ULTIMAX - Length: 54m remaining (for 5-6 uses) - Thickness: 0.65mm - Brand: YONEX - Color: Metallic White
