It's going to be a big soccer summer this year so why not throw a soccer theme birthday party for boys or girls and start it off with the Soccer Ball Pennant Banner. Each banner is twelve (12) feet long and made of an all-weather poly material so it can be used outside as well as indoors. The green pennants have a traditional black and white soccer ball printed on both sides and this soccer decoration matches our other decor like the soccerball whirls, the soccer party tape, and the large soccer ball cutout.
