Royal Classics RC20T Futura Nylon Guitar String Treblepak, Medium Tension

In one word beware. We are human not allowed to make mistake however, it is probable to do so. YOU ARE ONLY BUYING THE TREBLE SIDE. Only 3 string. for that 2 stars are all I can give. Nylon string mostly due to change in temperature and tension break at D string. This is a useless buy well thought by a crook. AVOID.
