Here is an original gift for those who love to go to the mountains. A whistle can always come in handy in dangerous or out-of-control situations. If you have a son who often climbs mountains on his bike, for example, this key ring will be convenient to attract the attention of another climber so that he can help him. If he falls, if something bad happens to his bike or, in any other situation, it is important to be able to call for help. In the mountains, having a signal is never something that is guaranteed, so an engraved whistle keyring like this one can be very handy. Before you pay, we'll ask you for the text you want engraving so that we can personalise the product as much as possible. You can also choose from three colours: blue, black and silver.
