Celebrate a birthday party with these fun jumbo mylar balloons! They are almost three feet tall! Pair them with our 16" 'Sweet' balloons gold or pink to make a special 'Sweet 16' set. They 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!
