Ernie Ball 2723 Cobalt Super Slinky Guitar Strings are round-wound for maximum clarity and serious punch. The Cobalt Super Slinky set is clearly an improvement on its classic nickel-wound counterpart giving the player increased sustain, clarity and output. In addition, they resist sweat and moisture better and have unmatched flexibility when compared to other nickel wound strings.
