About the Open Envelope Flap black filled 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 solid black filled version of the open envelope flap icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
