All the plastic coat hooks here are made of nylon. Nylon is a very durable, but inexpensive material. Further, the colored hooks are colored all the way through, so scratches aren't obvious. The flexibility of the material itself means that the coat hook is unbreakable. It might bend under heavy loads or abuse, but it's not going to break. So, plastic coat hooks are relatively inexpensive, come in an array of colors, and are almost indestructible.
