This is Daesung from BIGBANG's flash ring. I bought it at the live venue several years ago. I have kept it carefully. I turned it on once right after I bought it and once for this listing to check the light, but other than that, it's unused. It's in beautiful condition with no noticeable scratches or stains. I will ship it with the batteries removed. You can insert the batteries by turning the part where you put your finger through. It requires lithium batteries (CR1220 x 2). I will include the insulator. Please refrain from purchasing if you are nervous or seeking perfection, as it has been several years since the purchase m(_ _)m Immediate purchase is OK! Please feel free to comment if you have any other questions. I am also selling a lot of BIGBANG goods, so please take a look if you'd like ^_^
