I bought this as a token wedding gift for a young couple. it's a little crazy but that's what they like. still small enough to display in a cabinet, hang on a door, around a neck and blow or hide it away if they want too.
I bought this for a friend's hen do and ended it up not giving it to her. It came in different packaging and was poorly made. It's also massively large. Not a normal whistle's size. Save your money and buy something else to amuse your hens.
