The EFFECTOR 20th Anniversary Model is the "MUNAKATA FULL UP," an upgraded version of the popular "MUNAKATA" model. This model features a design inspired by the printmaker Shiko Munakata. Key Features: Design and Thickness: While maintaining the vertical, shallow Wellington shape of the base model "MUNAKATA," the frame thickness has been "fully up" from 8mm to 10mm, achieving an overwhelming presence and a sense of weight. High-Quality Materials: The 20th Anniversary Model uses 10-karat solid gold polished rivets, enhancing the sense of luxury. Details: There are color variations that feature clear material on the front side, allowing the temple (arm) core wires to be visible from the outside, demonstrating attention to detail. Production: Each pair is carefully finished by craftsmen in Sabae City, Fukui Prefecture, a renowned eyewear production area in Japan, ensuring a comfortable fit. The lenses are clear lenses without prescription. Blue lenses are non-prescription lenses for sunglasses. Comes with an EFFECTOR case.
