I found this while organizing my storage. I'm selling it because I don't use it. [Product] BOSS PSM-5 Power Supply & Master Switch [Condition] Only the lamp lighting up with an adapter has been confirmed. I haven't performed internal checks or professional inspections due to the lack of a suitable operating environment. Since the operation hasn't been confirmed, it's being sold as junk. I don't have specialized knowledge, so I may not be able to answer questions. There are no major noticeable scratches or stains, so I think it can still be used. (Please check the photos) Please check the images for scratches and stains. I try my best to look for scratches, stains, and dust that don't appear in the photos, but there may be scratches, stains, or dust in areas not shown in the pictures. This is junk, so please confirm everything before purchasing. Also, please refrain from purchasing if you are concerned. [Included Items] Everything in the photos. *Adapter not included. [Notes] ⚠️Please refrain from purchasing if you are nervous, as this item has been stored at home. ⚠️I make every effort to inspect the item before shipping, but please understand that there may be small stains or scratches. ⚠️Returns are not accepted for reasons such as "different from the image."
