About the Closed Envelope Flap black outline icon
A horizontal rectangle with the back flap folded down, its two diagonal edges meeting in a shallow V at the center to form the classic sealed letter shape. Clean and unmistakable, it stands for mail, messages, contact details and newsletter sign-ups, and works well in inbox buttons, app navigation bars, website footers, contact forms and email marketing slides.
Proportions follow a wide letter format, so the flap triangle stays readable and does not crowd the corners. Pair it with inbox, send, paperclip and notification bell icons for a consistent messaging set. Use it at 24 px and above; below that the flap lines start to merge.
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.
