Designed to make a BIG statement, these large-scale balloons are AIR-filled décor with 2 inflation points: one for the top shape & one for the base. · AirLoonz can be easily filled with an air inflator or hand pump. · Each package also includes an easy to place elastic strap. · The base is separate component so can be used with base as a standalone piece or without base as part of larger décor design. · The balloon base stabilizes simply with placement of a weighted household item (i.e. unopened can of soup or soda pop) in the provided space.
