Set of foil balloons in the shape of a butterfly, 21 pieces. The set includes 21 balloons, 7 pieces in three beautiful colors: light pink, gray-blue, and light blue. The balloons measure approximately 26.5 x 24 cm (10.4 x 9.4'') before inflation and approximately 19 x 23 cm (7.5 x 9'') after inflation. They are suitable for air inflation, and the set includes a straw for easier inflation. Thanks to self-sealing valves, you don’t have to worry about maintaining their inflation. Each balloon features two hooks that make it easy to attach to garlands or other decorations.
