About the Closed Envelope Flap black outline icon
A wide rectangular envelope shown sealed, with the back flap folded down so two long diagonal seams meet in a shallow V at the center and two more rise from the lower corners. It reads instantly as mail, messages and correspondence, which makes it a dependable choice for inbox buttons, contact forms, newsletter signup blocks, email marketing slides and app navigation bars.
The rectangle sits on a balanced landscape footprint, and the seam lines divide it into four clean triangles that hold their shape when scaled. Pair it with send, inbox and attachment icons for a consistent mail set, and keep it at 20 px or larger so the flap lines stay separate.
This is the black outline version of the closed envelope flap icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
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.
