D'Addario XSAPB1253 Phosphor bronze strings for acoustic guitar, Light, 12-53

Setting XS apart from other strings is the new, impossibly thin film coating (1/10 the thickness of a human hair) that completely protects the wound strings from corrosion, without dampening the tone. This new film covering is combined with D'Addario's proprietary dispersion coating, used in our XT line, to protect the plain steel strings as well.
