BTS JIMIN Solo Album Face Mini CD Keyring The mini CD has NFC functionality, and when held up to a smartphone, it will take you to the official YouTube video. Operation confirmed. Even if your smartphone doesn't support NFC, you can still use it as a keychain. I received this as a gift, but I'm selling 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, etc. I will pack it carefully and ship it via Mercari. Group Name: BTS Member Name: Jimin Item/Type: Keyholder
