MagicArch balloons are great for making quick mylar foil balloon arches. Each piece is one quad cluster that is inflated to be inserted into a balloon arch or balloon column. These can be used to assemble an arch in a fraction of the time required for traditional latex balloon arches. Requires 40 of the large size to create an 11 x 9 foot arch. They are also popular to be used as bases for other balloon decor. Mix and match colour or use complimenting color combinations.
