Ideal for dog tags, prevents the eternal clatter of brands together

So, I've been looking for something I can prevent the rattle of dog tags together. Thanks to a friend I got the idea to try it with key caps made of rubber. Unfortunately, the dog tags, however, are larger than a normal wrench head. Since my dogs each carry 3 marks on the collar (municipality, Tasso and pet collar) rattled it at every turn, what bothered not only dogs but also me. After a long search, I finally found rubber rings that fit around the brands. The brands have a diameter of 30 and 31 mm. Of course it was not easy to get the rubber rings (29 mm) on the brand, but if you then properly expands the rubber slightly heated (10 minutes in your pocket) and applying a little patience, then it works. I for one am thrilled because now we can at rest and while going literally walk.
