3sixteen’s SP-05 frames introduce a bold, architectural silhouette to their growing eyewear program. With sharp geometric angles and a substantial build, the SP-05 carves out a more aggressive stance while still carrying the refined minimalism that defines the collection. Made in Japan using premium Italian acetate, each pair is hand-finished to juxtapose polished and raw textures: the face and temples are glossed to a mirror sheen, while the frame tops, temple tops, and lens bevels are left raw for a tactile contrast. Utility details include a wide bridge, anti-slip grooves at the temple tips, and robust steel hinges with a three-screw mount for long-term durability. 100% Italian acetate Hand-polished face and temples Raw, unfinished bevels and upper surfaces Three-screw steel hinges for durability Temple tip grooves for anti-slip grip Subtle temple logo branding Geometric frame shape with wide bridge Frame width: 140mm Lens width: 47mm Bridge width: 24mm Handcrafted in Italy
