One of the coolest parts of the Reverse-Flash last season was that he got to use a Flash Ring. Now in the comic book world Barry Allen has long used a Flash Ring to conveniently keep his hero outfit discreetly with him, but the TV Scarlet Speedster has yet to incorporate this into his costume. Going forward, it looks like the concept of the Flash Ring is one that will be used by the Sultan of Speed at some point in the future, which is a mighty cool idea for long-time comic book fans.
