**[Regarding the Condition of this Item]**

I am selling this item because I haven't had much opportunity to use it, despite purchasing it at the end of November 2024.
I've only used it a few times at home, so there are no visible scratches or damage. The sound is also faultless.
The box is not included, but I will ship it in the included bag.
