About the Open Envelope Flap black outline icon
The envelope is shown open: the back panel stands upright, the wide triangular flap points up above it, and two diagonal folds meet at the bottom where a letter would slide in. It signals mail that has been read or is ready to send. Fits inbox screens, contact forms, newsletter signup blocks, email marketing slides, and support footers.
Built from straight lines only, the flap forms a tall triangle roughly as deep as the body, which keeps the silhouette balanced on a square grid. Pair it with closed envelope, paper plane and bell icons. Keep the stroke even so the folds do not look crowded.
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.
