About Product: Nylon is more resilient and tends to hold its tune better, and it is also much more resistant to changes in climate conditions like temperature and humidity. Nylon Core classical guitar strings deliver full-range tone with precise intonation and great projection. The clear treble strings are made of high-grade crystal nylon so you get the best sounding and playing strings possible. Silver-plated copper alloy wound basses use a multifilament nylon core for bright tone. Normal tension strings give you rich tone and dynamic projection. This set utilizes three crystal nylon trebles and three silver-plated copper wound basses for exception balance between strings and a great projection. With anti-rust coating, these strings last much longer (compared with uncoated strings).
