These are self-inflating balloons! That's right, self-inflating! You don't have to manually blow up these guys; you just wack the bag, and they inflate themselves. (We actually just press the disc in the bag until it pops and expands.) Pure genius!
They're very cool - literally and figuratively. You can actually feel a coldness to the balloon when it first inflates! And the bonus is that they last a decent amount of time, too - sometimes as long as a month! They measure approximately 3 3/4" when inflated. While they come in three different designs, we will make the choice for you.
What a great augment to any of our 3D greeting Valentine's Day card gifts!
