FastScoop ball is made of leather or syntetic fabric and its full of round shape plastic granules. It weights 65 g and it’s a bit smaler than tennis ball. (Official balls radius is 55 mm.) It feels like a footbag or hackysack but it’s developed to fly straight and keep it’s shape while it’s flying from Scoop to Scoop. It doesn’t bounce. Don’t let this little guy out of your sight.
