This is the Plus 1 Miesiąc 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 is an icon representing plus one month. It has a calendar made up of two differently sized rectangles. There are two small rectangles on the top of the calendar where the rings would be and it has + 1m written in the center.
