These Martin studio/performance strings are made by Martin Strings craftspeople from an ultra-high quality steel core that resists breaking much better than average strings. Both the core and the plain strings are plated with a smooth acoustic bronze finish. They stay bright, have long lasting tonal qualities, and look absolutely beautiful on a guitar. Gauges: 12-16-25w-32w-42w-54w.
