Masunaga® TAKA Eyeglasses by Masunaga®. Color: 31 GP/SILVER, 25 BL/AT-S, 19 BK/GP, Size: 53-18-140. TAKA's solid texture and dignified silhouette make your heart thrust. By creating a space (margin) between the rim line and the inner rim, we express the Japanese sense of aesthetics, the "aesthetic between", and the shadows and light and darkness created by the two parts. #31 is made from gold and the inner rim is silver, giving off a complex shine and giving it a distinctive look.
