i have been purchasing these awesome, beautiful, colorful, fun discs for years - starting with my kids when they were little (they just got new & they're now in their 30's) for people of all ages and personalities. i'm in my 70's. everyone has been enthusiastically excited ... even a 3 yr old who promptly wore it as a hat! inside or outside, dorms, apartments, homes, back yards or parks, or in the street ... (they always go to the beach) ... the play is wild, crazy, fun - or quiet, gentle tossing over conversation. we've done it all and will continue to recommend these to everyone! great company, great product!
