Flexocore Contrabass Strings, Set of 4

Thank you for looking.
This is a set of 4 Pirastro Flexocor double bass strings in orchestra tuning. After purchasing them used for 1 year, I used them for about 1 year and then removed and stored them at home.
There are some frayed areas on the winding due to being attached and detached several times. No fraying is visible on the metal parts.
I believe they are in good working condition, but please understand that they are used items.
They give the impression of producing a clear sound with good volume. Articulation is good and there is less strain on the left hand. How about trying them out?

Manufacturer: PIRASTRO
Type: Flexocor 4-string set (GDAE)
