Special application silicone nose pads
System "3" is a special application nose pad that is only available in a silicone material. It looks like a slide-on nose pad for rimless frames but actually mount similar to a primadonna and snap-in combined. This nose pad mounts into a square opening in the nose pad arm. You would insert the smaller end of the nose pad into the opening where it sets in like a gasket seal would on an appliance. The middle of the nose pad has a smaller circumference just the size of the hole in the nose pad arm. The large side is for the nose support. Not many eyeglass frames carry this type of mount. However, you'd would recognize it if it did. Reminder; Check your eyeglass frame mount before any replacement nose pad order. it is very important that you are getting the proper nose pad that will attach to your frame.
