This is the Nie wolno wkładać 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 a picture of a logo for Do Not Insert. The shape of the icon appears to be a cup like object. The object has an arrow pointing down in the middle of it. There is also a slash through the entire icon.
