Celebrate special occasions like birthdays with a festive balloon like these! Square foil balloons add a whimsical touch to flower arrangements, baskets, or gifts... or create a giant balloon bouquet of birthday wishes. Plus, sturdy foil material holds helium longer than latex balloons and cannot be easily popped. Balloons arrive uninflated; however, foil balloons purchased online can be inflated at your local Dollar Tree store. Due to the nature of helium supplies, it is important to please schedule with the store manager so as to make sure the store has the helium necessary to fill your balloons. Also, please present a copy of your purchase receipt when entering the store to have your balloons inflated. Balloon prints may vary, but theme will remain the same.
