This is a BIGBANG Taeyang flash ring. I bought it at a concert venue several years ago. I have kept it carefully. I used it once right after purchase and once to check the lights for this listing, but otherwise 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. 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 ^_^
