Celebrate a birthday party with these fun mylar balloons! These silver balloons spell out "Happy Birthday" and can be inflated by just blowing into them - no helium needed. Balloons are a fun and inexpensive way to decorate your home, hotel room, car, or restaurant for any party. Tie a ribbon in the birthday colors to the bottom of this balloon for an added touch. Please note: These mylar balloons do not come inflated!
