It is a simple introduction and review so that it will be helpful for those who are going to buy from now.
It is characterized by having a tubular shape containing contact notes for emergency situations. The part occupied by whistle is small correspondingly, the sound is thin and small.
Although the price is very cheap, I think whether it can be difficult to rely on when it becomes a scene to use this.
Since it is not necessary to be cheap so far, if you raise the rigidity and volume of the material, you may buy it even at around 1000 yen.
