➿ Double Curly Loop

Two curly loops, which represent a reel-to-reel tape recorder. Used as a symbol for voicemail on many phones. A variation of this logo is used by Free Dial, a toll-free telephone number by NTT in Japan. Can be used to suggest repetition, as per the phrase ‘on loop’, meaning to play over and over again. May also be used to reference a loop-the-loop on a roller coaster.
