Saving the world can get tiring, so make sure superheroes in-training stay hydrated by serving them drinks in these Justice League Party Cups. Featuring kids' favorite superheroes Superman, Batman, the Flash, and the Green Lantern, these paper cups will add some extra "POW!" to beverages at any child's superhero party or Justice League birthday party. Just fill them up with juice or soda to keep little boys energized to play pretend like their favorite superheroes after lunch. Or, try setting them around the table with plastic silverware and a paper napkin tucked inside to make place settings pop. Best of all, using disposable tableware will make cleaning up after the birthday bash feel like it was done at super-speed.
