This is the Pocztówka icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
The icon is shaped like a horizontal rectangle with a dotted line at its center. At the top right corner is a small square shape. Under the square at the bottom center are three horizontal lines, one on top of each other.
