Thomastik Infeld Belcanto Solo A & E

Thomastik Contrabass Strings, A and E strings. (High string side for solo tuning. Please note.)
These are the original strings that came with a contrabass I received. Based on the ball end color and information from the previous owner, they are presumed to be Bel Canto solo strings.
They were used on a full-scale contrabass.

They were used for over a year. (It is unknown when the previous owner last replaced them.)

I used the solo tuning strings (E, A) with normal tuning (G, D).
Both the previous owner and I only used them for jazz and never for arco playing, so there are no rosin marks and they are in relatively clean condition. After use, I wiped off sebum, etc., and regularly maintained them with String Life.
Therefore, the surface is still shiny. There is almost no roughness. (Personal opinion.)
However, as they have been used normally, there are creases and winding marks.

I replaced them this time because they felt like they were losing sustain.
I am offering them to anyone who would like to try them out, as they are still usable.
Compared to the new Spirocore strings I just put on, these have a warmer and gentler tone.

As these strings cannot be tracked by serial number, returns and exchanges are not possible.
