This is a frame made by HOYA (ホヤ) from the 1960s-70s. Furthermore, HOYA has withdrawn from frame manufacturing, making this a very rare vintage item. Although half a century has passed since its manufacture, the jet-black plated surface is miraculously free of scratches, and the degree of deterioration is considered extremely minor. The company ESSEL (エッセル) of France was the first in the world to release a frame that suspends and fixes the lenses with nylon thread (rimless), and HOYA imported and sold those frames in Japan. This product is one of those frames, and its excellent condition makes it an extremely rare item. It's nearly extinct now, and a find like this is hard to come by. This product is recommended for vintage enthusiasts!
