Hand made in America, the Wavy Chain footbag includes an outer covering of colored, anodized aluminum rings (the toughest aluminum alloy money can buy) with a nuggety center made up of silver alloy aluminum rings. Like any good freestyle bag this baby pancakes on impact for controlled kicks and stalls. Weighing in at 45 to 50 grams this is a superb addition to anyone's footbag collection. ** Color Combinations Will Vary **
