Pair of Dog Tag Silencers.
Made from gas mask hose, the same way GIs used to do during second world war to prevent dog tags from jingling on patrol missions (see original photos).
Only the rubber silencers are for sale, dog tags and chain are not included.
Price is for 1 pair of silencers (= 2 silencers).
Silencers might be a little stiff. To install them on your dog tags, immerse the silencers in hot water for a few minutes to soften rubber. Repeat the operation if neecessary.
