This is the Kontakt biznesowy 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.
A business contact icon is a rectangle, but it isn't complete because at the bottom there are two half like circles that looks like someone hole punched it. In the rectangle there are two symbols, on the left there is a person and on the right there is an at sign.
