This is a flash ring from BIGBANG's Seungri. I bought it at a live venue several years ago. I have kept it carefully. I turned it on once right after I bought it and once to check the lights for this listing, 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. Two lithium batteries (CR1220 x 2) are required. 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. Immediate purchase is OK! Please feel free to comment if you have any other questions. I am also selling a lot of other BIGBANG goods, so please take a look if you'd like. ^_^
