The Martin Tenor Ukulele strings are made with fluorocarbon for enhanced tone and playing durability. The density of Martin fluorocarbon is higher than traditional nylon, giving your ukulele a stronger and richer tone. The Martin Tenor string fluorocarbon formula also has longer elongation properties to resist tone loss caused by stretching of the strings under tuned-to-pitch tension. With the Martin Tenor Ukulele strings you can stay in tune and play longer!
