The Dirtbag Stellar Stallar footbag is an absolute one-of-a-kind. Not only is it the only footbag with a combination filler of sand, steel ball bearings and plastic pellets - but it's also a light activated glow in the dark footbag. Night time play is so much more satisfying when you can actually see the footbag. This 12-panel synthetic suede footbag is ideal for freestyle fun, 24 hours a day.
