About the Inbox black filled icon
This inbox icon shows a horizontal envelope drawn from the reverse side, with four triangular flaps meeting at a center point to form crossed diagonals inside a rectangular border. It reads instantly as mail waiting to be opened, so it fits email clients, message center tabs, notification badges, contact forms on a website footer, and support ticket dashboards where incoming letters need a clear marker.
Proportions follow a classic landscape envelope, roughly 3:2, with even stroke weight on the outer rectangle and the V-shaped flap lines. It pairs naturally with send, archive, trash, and attachment icons in the same set. At 16-20 px, keep the flap lines from thickening so the center point stays visible.
This is the solid black filled version of the inbox icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
