A check mark / tick that displays a white outlined appearance. Shows on most platforms with a bright green rounded rectangle or circle surrounding it.

Generally used to indicate completion, approval, agreement, or correctness. Commonly appears in checklists, confirmations, and to signal that something has been verified or successfully accomplished.

Android previously displayed this as an outlined blue check mark / blue tick as well as a large white tick. Samsung's design was also previously a large white tick, as was Facebook's.
