Meet Runbell: a cool wearable bell designed for urban runners. If you find yourself running in crowded areas, you may want to get a bell like this to avoid accidents. It is lightweight and easy to use. It has an adjustable design, so you can wear it on your finger conveniently. By using Runbell, you can give pedestrians heads-up that you are coming through. It makes a nice sound too. Like it? You can support the project on Kickstarter.
