Spirocore Viola String, A - medium from Thomastik-Infeld.
Spirocore strings are a technological advancement over conventional rope-core strings because they have a more flexible spiral core made of steel, creating a higher period of vibration than other rope core strings.
The hi-tech core makes for effortless fingering, responsive bowing, stable tuning and a very long string life.
The Spirocore viola G string is available in Chrome and Silver; the C is available in Chrome, Silver, or Tungsten.
