Ring, ring, on your left! Wait…it’s not a bike, it’s a runner! Now runners have their very own way to alert others when they are near. It’s called Runbell and is a stylish accessory to wear on your middle and index finger. Available in both a women’s and men’s size, the rings are slightly oversized so that you can wear them on top of gloves. Otherwise, there are silicone inserts for a snugger fit on bare hands. As they are made out of brass, there’s a clear and powerful sound that can be heard up to 20 feet away. Runbell, the latest accessory for the polite runner.
