This is the "MN Hinge" series, which uses the classic "Ichiyama", also known as a saddle bridge. The surface of the mountain has a classically engraved pattern, giving it a more atmospheric finish, and the back surface of the mountain, which is placed on the skin, is filled with clear cloisonné to make it feel soft against the skin. The MN spring mechanism creates a comfortable wearing experience without the feeling of pressure, which is not found in conventional classical frames, and it is a frame with a texture that is worthy of being called a ``modern mountain.'' Although it looks classic, its functionality is on a different level from the classic frames that are common.
