Flash ring

The Flash ring is a ring owned by Barry Allen that is used in relation to his Flash suit. It bears a lightning bolt symbol similar to the one sported on the Flash's suit.

History
In a possible future timeline, Ryan Choi designs and creates the flash ring, along with the fifth flash suit. They both eventually end up in the Flash Museum, and are then taken by Nora West-Allen and given to her father, when she travels back to 2018.

Functions

 * Storage: The flash ring acts as storage unit for the fifth iteration of the flash suit.
