The BLACK GEAR COG Men's Ring features a smooth edge cobalt band with a contrasting texture black gear cog design embedded at the center.
The comfort-fit design, which features a domed interior, provides all day comfort and is recommended for men because it is easier to slide over a large knuckle.
Size: Band is 5/16 inch (8 mm) wide.
