These small keyring whistles punch far above their apparent weight. They are ideal for dog walking, training, personal security or building a terrible relationship with the new neighbour who just moved in next door. They are metal, aluminium I believe, making them both strong and light weight.
You may see the same whistle shown as ultrasonic in other sellers adds, they are not so please don't be fooled!
The colours are being chosen at random from the ones shown in the images, plus some high gloss versions. But if you want to put in a request or check availability of a certain colour feel free to message me. As I am a nice guy if you put in a request post purchase (before posting) and I don't have the colour you requested I will happily cancel the sale and refund you.
I offer free 2nd class UK postage .
