This product is made by Sanko Optical, known for its quality craftsmanship. Sanko Optical is an eyeglass frame manufacturer located in Sabae City, Fukui Prefecture. This is a heavy and luxurious frame that uses titanium plate material generously, with a gold color as the base and a brown coating on the surface. I don't think there are many titanium frames with this much thickness. As a result, the weight increases, but the parts connecting the front frame and the temples are designed to flex, making it feel lighter (compared to other frames of the same weight). The front frame is processed by cutting out the titanium plate material, so there is no worry of the bridge breaking. This is a nylon rim (lenses are held in place with fishing line) type frame. Prescription lenses can be changed for an additional 3,000 yen or more. Please consult for details. Lens size: 53mm (width) 32mm (height) Nose width: 16mm Overall length of the front frame: 132mm Frame color: Gold base Brown coating on the front frame and temple surfaces Material: Titanium (as stated) Rubber metal Country of manufacture: Japan (as stated) Retail price: 34,000 yen (excluding tax) Although it is new and unused, please refrain from purchasing if you are concerned about minor scratches or stains.
