BTS JUNGKOOK Solo Album GOLDEN Mini CD Keyring The image is a sample of the whole item. Only one main item will be shipped. The mini CD has NFC functionality, and when held near a smartphone, it will link to the official YouTube video. Operation confirmed. Even if your smartphone doesn't support NFC, it can still be used as a keychain. I received this as a gift, but I will sell it to someone else who is looking for it. Unofficial product. This is an overseas product, so please understand that there may be initial scratches. I will pack it carefully and ship it via Mercari delivery.
