【High-Quality Frames】 999.9 eyeglasses use stylish designs and high-quality materials, combining durability and lightness for comfortable wear even over long periods. 【Stylish Design】 The "M" in the model number stands for "mix." Four Nines' mix frames are a series that has built Four Nines' unique style by blending various elements, not only materials but also the balance and mechanism of the glasses, and a sense of the times. The M-18 is a mix frame that combines the Four Nines style with current quality. Following the flow of "M-01" (released in 1997), Four Nines' first mix frame, it features a soft brow line created by the integrated plastic brow (※) and metal bridge. While inheriting this iconic style, the quality aspects such as the front structure have been greatly improved, elevating the frame to one where the harmony of different materials and the flowing brow line are more beautifully reflected. One of Four Nines' representative styles: "Brow Frame." A simple yet beautiful style where the frame draws a soft, flowing line from the bridge to the temples, connecting in a straight line. The metal bridge and plastic parts harmonize at a high level, creating a classic feel. 【Comfortable Fit】 The lens shape "Type A" has a rounded square form, giving a smart impression that is not too harsh. 【Comes with a dedicated case】 A case is included, allowing you to safely store your glasses. - Brand: 999.9 (Four Nines) - Frame Color: 6271-Pearl Dark Brown - Model Number: M-18 - Size: F□17-133 - Lens Size Type-A - Nose Width: 17mm - Temple Length: 133mm - Lenses: Prescription lenses are included, so please replace them with your own lenses when using. ※This is a used item.
