This is the Transfer pomiędzy użytkownikami 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 icon represents transfer between users. It is two people's head side by side touching at the shoulder. There are two dots under the shoulders with two lines making arrows pointing opposite, one left and one right.
