This is a great alternative to a regular balloon!
The central tube is designed to be filled with air by mouth and then you wave it around and make the wings flutter. Sort of like a butterfly light saber! The wings themselves are not inflated so they flutter very realistically.
They make great party favors and are a lot more fun for kids to play with! And you don't have to inflate them with helium.
Easy, convenient, and lots of fun!
Size: one butterfly, 29" in length and the wingspan is about 18"
