this i really a correct choice for your dinosaur party. dear clients we advise you to fill the balloons with air, to stick them to the background or just stick them to your party, as the desigh of shape, they can not fly up very well, if you want to make all the dinosaur balloon fly well, our balloon is not the best choice, but if you just stick them on your background or put as the decoration, they are the best and also can be kids' toys after party.
