Just like the 13 mm nose pads, these 10 mm nose pads take on the same shape, yet are 3 mm shorter. These are not the smallest nose pads available. Yet they are a good alternative to the 9 mm round style, if you are looking for a smaller nose pad. These are made of silicone material and are available in the screw-in and the snap-in mounts. Reminder: As with any nose pad order, please be sure to double check the correct mounting type needed for your eyeglass frame. Whether it be screw-in or snap-in. As for size, that is dependant upon one's own personal preference.
