Unique Industries Create an eye-catching balloon bouquet for your kids birthday with these Latex Despicable Me Minions Birthday Balloons. These latex balloons measure 12 inches when fully inflated. They ship uninflated and can be filled by mouth or balloon pump — or taken to your local party store to be filled with helium. Combine these balloons together to create a balloon bouquet — or if you re not using helium tape them to the walls sit them on the gift table or even scatter them on the floor. For even more Minions madness combine these balloons with the rest of our Despicable Me Minions themed party supplies.
