This keychain is a unique gift for him/her. Custom the code keychain, choose any song you want, all can be imprinted on the plaque, and you can generate a unique Spotify code. Please note that the plaque itself does not emit music. You have to scan the code on the app, after scanning the code, your song will start playing immediately. On any memorable day, I believe this is the most romantic gift, play the most beautiful music for your love.
