Collaborative sunglasses with JULIUS TART OPTICAL, based on the brand’s “AR” model—an authentic reproduction of TART Optical Enterprises’ world-renowned “ARNEL” frames from the 1950s–60s. The temples are engraved with both brand logos. Featuring vintage-inspired styling, the design uses 2Base lenses, known for their high reflectivity from the front that reduces eye visibility, while balancing a sharp look with visual comfort. Produced in a single 48mm size, available in two colorways: gradient frame and clear crystal frame. A special joint work with JULIUS TART OPTICAL.
