Masunaga VIVACE Eyeglasses by Masunaga. Color: 30 CLEAR, 29 BK TORTOISE, 19 BLACK, Size: 53-17-145. A retro lens shape reminiscent of the big shapes that were popular from the 1960 to the 1970 era. The front has a television cut, giving it a three-dimensional shape. By combining the refinement of MASUNAGA, including the use of slim metal temples, we have created an elegant finish that blends in with modern times.
