● This is a room mirror by Tsuchiya Yac. ● A mirror that incorporates the "natural sense of distance" of a flat mirror and the "wide field of view" of a curved mirror. ● Mirror surface size: 270 x 70mm ● Provides a field of view approximately 1.4 times wider horizontally than the original room mirror. ● Provides a field of view approximately 1.5 times wider vertically than the original room mirror. ● The 270mm 5000SR provides a field of view equivalent to a 300mm flat mirror. ● The vertical direction (70mm) is also curved, so the rearward field of view is approximately 5cm wider than in the vertical direction of the same size (flat 70mm). ● Uses a high-quality chrome surface mirror that prevents glare from headlights of following vehicles. ● Features a timeless black frame. ★ I am selling this because I no longer use it. ★ The condition is good and it is in very clean condition, so I think it is still perfectly usable. ★ Thank you.
