Details:Make playtime an adventure with these unicorn balloon balls! Like a balloon, you can throw it, catch it, squeeze it and bounce it...and like a ball, they are reusable and portable. To inflate, simply insert the included nozzle into the valve, put your mouth on the nuzzle and blow. Once you have reached the size you want (up to 9" diam.), remove the nozzle and the valve will self-seal. A "magical" toy for your young party guests, let the fun begin at your next themed event!
