Purple and white marble bowling ball, Roto Grip Optimum Idol Solid. Price negotiations accepted. I bought this for matches, but it didn't suit me, and I haven't thrown it even once. I really haven't thrown it at all, so there are no scratches. (The surface has been polished with Power Edge to prevent friction scratches. Please adjust the grit to your preference when using!) I thought it was a waste, so I'm putting it up for sale. - Brand: Roto Grip - Model Name: Optimum Idol Solid - Color: Purple/White/Blue marble pattern - Number of holes: 3 - Logo: Roto Grip #RotoGrip #OptimumIdolSolid #Idol Thank you for looking.
