DRAGON SKINâ„¢ Electric Guitar Strings feature DR's K3â„¢ clear coating on a nickel-plated steel wrap wire to prevent dirt and perspiration from reaching the hexagonal core wire, preventing corrosion. The K3â„¢ coating, which is applied to all strings in the set, is ultra-hard and doesn't dampen vibration like softer coatings can. The strings have more projection, fewer unwanted overtones, greater clarity and articulation than uncoated strings. <> String Length: 38" <> Material: K3 Clear Coated Nickel-Plated Steel.
