"These electrics do not feel coated, they are crisp and bright." The K3 coating is the first coating that players report sounds as good, or better, than uncoated strings". Players tell us Dragon Skin strings have more volume, less unwanted overtones, greater clarity and articulation that standard, uncoated strings. All 6 strings are protected against then elements, and feature K3 coated plain steel strings. Based on DR's unique round core construction with K3 coated NPS wrap.
