Huntsman Green Silicone Water Collar

My dog has worn this collar (in orange) for 8 years and it’s still perfect. Heavy duty for hunting, waterproof for swimming. I found these in a backstock box. There are some dirt marks on them as shown in photos. It looks like something bled in the box. The marks are on the back side of the Green collars. The only one left is the 17” with a mark on the front side shown in last pic. Will not detract from the function of these collars. Great for Yellow labs or retrievers. Brass hardware.
