If it's one thing we know, it's finely crafted and vintage instruments. We created our Marquis line to pamper your guitar by adding a soft silk wrap to the ball ends which prevent wear and tear on the bridge and end plate as you play. Our silk wrap puts a comforting layer of protection in place every time you change your strings. .011.5-.014-.023-.028-.038-.047 • MFSKU MA130 • UPC 729789557993
