☆ 999.9 S-671T ☆ Color: 2 Silver ☆ Lenses from 670T are installed. Lenses for 671T are also included. The vertical width of the 670T lenses is shorter, giving a sharper impression. Both have prescription lenses, so it is recommended to replace them when using. ☆ From the popular S-670 series, this is a representative style of 999.9 (Four Nines), a metal brow that is also one of the iconic designs of 999.9. It has been remodeled to suit the current trends and reconstructed with the quality available today. Unlike the complex structures of the S-320T and S-111T, this frame features a simple style with a balancer mechanism different from the reverse R hinge and a new double front structure, resulting in a frame that allows you to feel the condensed quality.
