When you wants lots of shine for your Prom or Homecoming dance, use these 11" Metallic Balloons. The stunning metallic finish of these latex balloons make them the shiniest balloons we offer. They're great for Prom themes that need some extra pizzazz--like Hollywood, Vegas, or crystal themes. The 11" diameter metallic finish balloons come in a package of 150 and can be used with helium or other type of balloon inflator. Mix and match your balloon colors to create clusters for a Prom pathway, cover a wire arch for Homecoming, or add streamers and balloon weights to them to create shimmery balloon bouquets.
