Nike Kobe ad, 28.5 cm. Thank you for viewing. I vaguely remember purchasing these from a sporting goods store about 10 years ago, and I used them about 4 or 5 times. I haven't used them since, and I don't plan to use them in the future, so I'm putting them up for sale. There is some minor soiling. Please refrain from purchasing if you are concerned. I will pack them in the box shown in the photos and ship them with cardboard and other protective materials.
