Thomastik Infeld Belcanto Solo E & B

Thomastik Dominant Double Bass Strings, 3rd and 4th strings.
These were the original strings on the double bass I received. Based on the ball end color and the previous owner's information, I suspect they are Bel Canto strings for solo tuning.
They were used on a full-size double bass.

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

They were used for solo tuning with normal tuning.
Neither the previous owner nor I used them for arco playing, only for jazz, so there are no rosin marks and they are in relatively clean condition. After use, I wiped off sebum and other residues, and regularly maintained them with String Life.
Therefore, the surface is still shiny.
However, as they have been used normally, there are some creases and winding marks.

I replaced them this time because they seemed to have lost 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.
Since these are the lower strings, they should be easy to get used to.

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