The core of this Regal and sophisticated buckle collar is highly dependable 600-lb. polypropylene webbing. Our signature CuddleSkin satin lining will completely wrap the core to eliminate raw edges and protect your pet's neck. Each seam is created with an industrial-duty heavyweight bonded nylon thread. Every Classic Hound dog collar comes equipped with military strength metal casted brass and nickel-plated brass hardware. Each slide and every welded steel D-ring is individually inspected before it is sewn tightly into place. Our heavy duty cast aluminum side-release buckles have an average break strength of over 500 lbs, yet remain lightweight and sleek. Hand wash this fancy collar in COLD water with mild soap, air dry only.
