This is the Zwrot książki 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 square with a rounded top left corner and two pointed corners located at the top and bottom right. The bottom left corner curves off to form a long oval shapes that runs the whole bottom of the square but doesn't close on the right side.
