Refill per unit - Round yarn 85
A folk guitar string purchased in units of 0.85 gauge refers to the thickness of the string. The draw of the string indicates the amount of tension exerted on the string, measured in units of pounds (lb) or kilograms (kg). In this case, the draw of 0.85 corresponds to a tension of 0.85 pounds or 0.385 kilograms. Folk guitar strings are generally available in different gauges to suit the preferences and playing style of each guitarist. Strings with a higher tension will have more tension, which will give a stiffer feel when playing and can also produce a louder, brighter sound.
