This product was retired in May 2018. This is the simplified version of the K-10 collar. It may not pack the same punch as the K-10, but if you need to use the cordage, you simply unweave it and still have an intact collar to use on your dog. It's a piece of cake to re-weave any color of paracord you have on hand, so it's the perfect foundation for those that struggle to decide on colors. All you have to do is take a few minutes to put some new paracord colors on it and your dog can have a whole new look every week if you want! WHY DO I NEED ONE? Because your dog is wearing a collar already, why not make it useful? Keep your best friend visible and safe with the glow tape and full length 3M reflective Biothane.
