Item number 9020272,
This set of Folkcraft brand dulcimer strings will keep your instrument sounding great. These loop end strings come in a set of three with the following gauges: .012, .015, .024RW).
If you play your dulcimer set up with three strings (instead of four), then we're recommending these gauges - the balance across the strings is better for three-string players. (Some people take off the extra melody string of a four-string dulcimer string set, and play with 011, .013, and .024RW, but the slightly heavier gauges of our optimized three-string set are better for most players and most instruments.)
