Pick up this great gift idea. Running through the city is tough enough without walkers on shared pathways getting in your way. Politely let the strollers in front of you know you need to pass through in a hurry with the Runbell a sleek and stylish ring that works just like a bike bell. Rather than muster up a holler in your already huffy state simply give the bell a ding to alert pedestrians in a friendly way. The two-finger ring can be adjusted for a comfortable fit with the silicone inserts to keep it from sliding out of place. Made of brass and aluminum in Tokyo Japan. Essential Details: Made from aluminum brass Measurements small fits ring sizes 6.5 - 11; large fits ring sizes 10-15 Notes: Care: Keep Dry. The rings are slightly oversized so you can wear gloves in the winter. The metal is allergy free. Be polite and courteous when passing pedestrians on trails and city sidewalks.
