This is the Współrzędna Z 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.
This seems like a Logo but looks more like a keyboard button. It has the a square with the letter Z in the middle. This icon can be similar to the icon or logo of that of a social media icon. But similarly to the keyboard tabs.
