The Collapsible Stadium Horn is long like a trumpet. With practice you can make sounds like heard at the stadium. The horns start off at 15.5″ long and when extended are approximately 29″ long. The width of the horn (on the larger side) is approximately: 4 1/2″. There are many colors of collapsible horns to choose from. Please note: These horns are brand new, but they come from overseas and they are not in “perfect” gem mint condition. It is however, just a plastic horn — usually there are just some small bend marks on the thick portion (barrel) of the horn.
