This is a rare, patented eyeglass frame that uses a unique structure to support the glasses with a part of the ear, which is no longer widely sold. It seems that the patent was still pending when it was first released. Model Number: PS-31H Color: BL-L Size: 48□19 *Special price due to missing parts. Normally, the temple tips are inserted into the ear and hooked in place, similar to nose pads. (It's surprisingly stable even if you rest it along the scalp above the ear. It might be okay without inserting them.) Search for "Prostyle eyeglass frame" to see photos of people actually wearing them. Recommended for those with a long distance from the eye to the ear. Also recommended for those who often experience ear pain. This is a special price because it's quite old. Although it's new, the silicone parts have also discolored. Since this is a dead stock item, we cannot guarantee future use. Please purchase only if you understand the above. Manufacturer's suggested retail price: ¥31,500 (tax included) Color: Blue Frame Material: Metal
