About the Open Envelope Flap black outline icon
An envelope seen from the front with its triangular flap folded upward and open, showing the empty pocket and the two diagonal creases that meet in a shallow V at the center. It signals mail that has been opened or read, rather than a sealed message waiting. Useful for inbox read states, newsletter sign-up blocks, contact sections, email verification screens and notification centers.
The shape is a wide rectangle topped by a tall triangle, with interior diagonals meeting at a low center point that gives the envelope depth. It reads as a natural counterpart to a closed envelope icon, so pair the two for read and unread toggles. At small sizes, check that the inner diagonals do not merge visually.
This is the black outline version of the open envelope flap icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
