Perfect for fancy dress parties! This Inflatable Sumo Costume will inspire a fun filled night of wrestling with your friends - and with a battery operated fan that keeps it inflated for up to seven hours per charge, there is plenty of time for fun and frolics. Easy to inflate and put on: Simply step into the costume, turn on the fan (discreetly hidden inside the outfit) and you will be fully inflated within 60 seconds. And, as it is made of a lightweight material, it won"t stop you from dominating the dance floor. A sumo hair hat is included to help you really look the part. Batteries: 4 x AA batteries required (not included)
