A bell application of bear avoidance.I make a spectacular showing by popular mountain climbing recently.It’s recommended to a mountain girl, too!It’s different from a real bell and it’s possible to turn on after I enter a mountain.This doesn’t stand out in the train.But, the effect equal to a real bell isn’t secured, so I’ll put it on the bear to see the corrective action when being attacked.The battery for a cell phone is important by mountain climbing. Please often think and use it.
