BTS arirang interactive NFC mini CD keychain! Front and back of CD pictured. Plays a song of your choice on Spotify, Apple Music, or YouTube when you tap your phone to the keychain. Message with the song you wish to be programmed and what music service you use. Android and iPhone compatible. I have a version with member cover art in another listing! Keychain is designed to be kept closed - nothing to see inside! (: #kpop #gifting #btsarmy #keychain #bangtan
