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 the patent was still pending when it was first released. Model Number: PS-14T Color: BRM-S Size: 49□18 It is used by inserting the temple tips, which have nose pad-like parts, into the ear and hooking them. (It surprisingly stays in place even if you put it along the scalp above the ear. It might be okay not to insert them.) Search for "Prostyle eyeglasses 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 from a long time ago. 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: Brown Frame Material: Metal Color: Brown Frame Material: Metal
