Zyex Composite synthetic core strings produce an extremely warm, rich sound. Zyex is a new generation of synthetic material, creating strings that are extremely stable under drastic climatic conditions. Zyex strings settle in on the instrument very fast, within a matter of hours. Zyex has a warmer sound than most other synthetic core strings, and they have excellent projection. Ideal for producing a more professional tone from student-quality instruments. The 1/16 scale strings are gauged specifically for 1/16 size violin with a playing length of 8 1/2 inches (216mm).
