13mm clip on mount nose pad in a soft pvc material. These are just like the many small clip on mount nose pads found on RayBan eyeglass frames. These are the smallest clip on mount nose pads available. They come in the traditional silver mount as this is the only color option for this size. Because of their material, they have some flexibility to them and are not like the some of the hard plastic nose pads often found associated with this style mount.
