This is a rare, patented eyeglass frame with a unique structure that supports the glasses using a part of the ear, which is no longer widely sold. It seems that it was still patent pending at the time of its release. Model Number: PS-30H Color: LBR-L Size: 50□18 It is used by inserting a part like a nose pad at the end of the temple into the ear and hooking it. (It surprisingly stays in place even if you put it along the scalp above your ear. It might be okay not to insert it.) 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. It's quite old, so it's a special price. Although it's new, the silicone parts are also discolored. As it 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 yen (tax included) Color: Brown Frame Material: Metal Color: Brown Frame Material: Metal
