These sports sunglasses were purchased for use with a radio-controlled model, as I wanted to see the aircraft clearly. Two frames are included, and five different lenses can be interchanged: polarized gray, mirror, yellow, blue, and clear. I hardly used them, and now I need to use prescription sunglasses, so I'm selling these. Includes a hard case and instruction manual. Everything in the photos is included. The hard case is thick, so it will be shipped via Takkyubin in a 60-size box, with shipping costing 750 yen.
