The Mailbox 2 icon shows a rounded blue mailbox with a black outline, a white horizontal slot near the top, and a white triangular shape centered inside. Drawn in the creative style on a 40px grid with a 1px stroke so its colorful forms stay clear at small sizes. Use it for mail controls, inbox navigation, message centers, postal services, and delivery tracking. It belongs to Stickies Colors set in the Streamline Vault family.
