Dog Tag Silencers are made from flexible colored silicon and can be attached to dog tags to improve comfort and mobility. Another benefit of the silencer is realized in hot climates or during summer, when stainless steel may heat on open sun. Each dog tag requires its own silencer. The picture shows silencers in a round shape. This is a shape in the free state. After the silencers are stretched over edges of dog tags they take the form of the dog tag.
