Running over the car special ring: Runbell ring ring
Designed for people who love running, it's very simple and works like a bicycle bell.
The "Runbell" is made of all-metal, and the main bell is made of brass, which is very durable. Simply put it into your finger and use it. When you move it, you can make a loud ringtone and tell the passers-by in front of you. Please “make itâ€, so you can avoid the mouthpiece, similar to the function of bicycle bell.
I think there should be other uses besides running, it depends on how the user plays.
