Thank you for viewing! None of these have been used live since I purchased them. They have been stored at home for a long time, so some may have dust. Please check the photos. I have wiped them as much as possible. Please refrain from purchasing if you are concerned, as they are stored by an amateur. Regarding the operation, only the last two in the first photo light up, but the others have not been confirmed. I don't have a screwdriver, so I can't open them to check. Some can be opened, but I haven't confirmed them because they don't have batteries. Since they are not in perfect condition, I would like you to consider them as junk. I love SixTONES and will be posting more goods I have collected in the future! Instant purchase is OK.
