Self Defense Emergency Whistle With Key Chain

Our survival whistle adopts a flat shape and is as portable as a card. You can put it anywhere in your backpack or in your pocket, and it will not occupy your backpack. There is a key chain on the top, so you can hang the whistle on your backpack for immediate access. Can be used for survival, wildlife repelling, camping, hiking, backpacking, archery, fishing, swimming, boating, kayaking, marine sports events, any type of outdoor activity, and can also be used for dog training. The multi-audio design can make the whistle sound more discernible and achieve better emergency survival effects.
