The Align Back 1 icon shows a large rounded square layered over a second rounded shape offset down and right, with a light inner fill and bold blue outer areas. Drawn in the duotone style on a 14px grid with a 1px stroke so the layered forms stay distinct at small sizes. Use it for send-to-back controls, layer ordering, object alignment, and design or editing interfaces. It belongs to Core Duo - Free set in the Core family.
