Chromesteel on synthetic core.
All strings are ball end, full size, medium tension unless specified.
1 out of 2 found the following review helpful
Pros: Lovely mellow sound on my old cello (& on starter student instrument 3/4 size)
Cons: Doesn't stay in tune for first few days
Other: You advised me not to put on a smaller instrument - but it worked in this instant, the wire covering not reaching the pegs.
