Hi, I'm selling three used strings that are about six months old and in very good condition - these are the standard strings used by orchestral players and sound great on pretty much all basses:

Pirastro Original Flexocor G - $18
Pirastro Original Flexocor D - $23
Pirastro Original Flexocor A - $28

All three are medium gauge. Please message me if you're interested, thanks!
