This is the Pochwa 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 two parentheses facing each other but not fully touching. Inside directly in the middle are another set of parentheses but this time they fully touch. Inside of that one is another set but they aren't in the middle, they are towards the bottom.
