These traffic cones are made with a special resin that prevents them from sticking together. Therefore they pull apart easily, which is important to saving labor time and effort. 60% of the black base is made of recycled materials and are warranted to never separate from the cone. Traffic cones are "pure orange" which means they are orange through and through, and not orange over white resin. They keep their color longer than other cones. Traffic cone collars are made with the highest quality 3M™ sheeting and are recessed in cones, to prevent them from coming off. New handle top feature makes it easier to grab cones.
