Used viola strings. A D G strings: D'ADDARIO Kaplan AMO C string: EVAH PIRAZZI Tungsten-silver-medium Used for about 12 months. (They were strung for the first 6 months, but the instrument they were on was not used.) Please purchase only if you understand that these are used items. I didn't see any fraying of the winding. In the case of my instrument, I wanted a powerful sound from this C string, so I chose EVAH PIRAZZI Tungsten-silver. The A string harmonizes with the other strings, but you need to be careful with the amount of force. They have been cleaned with isopropyl alcohol and are stored in the paper cases of other strings. *Please note that we do not accept price negotiations.
