Bowling ball with a blue-purple marble design, PHYSIX model. - Brand: STORM - Model Name: PHYSIX - Color: Blue-purple marble - Number of holes: 3 Thank you for viewing. I obtained this as a prize in a tournament and tried it out, but it didn't suit me, so I'm putting it up for sale. I've only thrown it about 20 games, so it should still be usable. There are some scratches, but there are no problems with use. Please note that this is a used item, so no claims or returns are accepted.
