This is the Pożycz książkę 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 the top left corner being curved and the top and bottom right side corners being pointed. The bottom left corner curves into a oval shape that runs the length of the square but doesn't close at the end. Inside the square is an arrow pointing down with 3 dots at it's tail.
