Browse all the balloons and accessories for sale at SillyJokes right here. We have hundreds of choices so it could take you some time but you should be able to select your colour on the left . Remember 5 inch balloons are very small, about the size of a coconut and are useful in making displays and decorating your balloon weight but won't float with helium. 11 inch balloons are the ones to make floating bunches or air filled bunches for the walls and doorways. You can fill our balloons with either air or helium but if it has a design pay attention to the way up it is printed. You don't want it to float upside down.
