The Maximize 1 icon shows four separated, rounded corner marks arranged around an open center, with a pale secondary color inside the lower-left form. Drawn in the duotone style on a 14px grid with a 1px stroke, it keeps the curved geometry clear and airy at small sizes. Use it for maximize controls, fullscreen views, image or video expansion, and spacious workspace layouts. It belongs to Flex Duo set in the Flex family.
