Dye Sublimation webbing collars rock! This vibrant and colorful "fabric free" collar, is made with a silky smooth polyester webbing that was printed on both sides, using a dye sublimation process. The ink has been permanently infused into the material, creating not only an amazingly vibrant design, but the colors WILL NOT FADE! It is also UV, rot, mildew, and MOISTURE RESISTANT. We are in love with this super-strong and durable material, and we know you and your pup will love it too!
