Open Envelope black outline icon

About the Open Envelope black outline icon

This open envelope icon is drawn front-on as a rectangle with the large triangular flap folded down over the face, its rounded peak rising above the top edge and its point dipping into a small notch at the center. It communicates opened mail, read messages and correspondence. Use it for read-state markers in inboxes, newsletter signup blocks, contact sections, notification panels and support or help-desk screens.

Clean diagonals from the lower corners meet the flap point, giving the icon a symmetric X composition that stays crisp at any scale. The rounded flap apex is the detail that distinguishes it from sharper envelope variants. Pair it with sealed envelope, paper plane and inbox icons, and use it at 20px or above so the center notch remains visible.

This is the black outline version of the open envelope icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
