This is the Dymek info 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.
It is a speech bubble with the letter "i" in the center. The bubble is not an exact circle, but rather a horizontal oval. The letter "i" is lower case, and one would think that by seeing this icon you would be informed about a certain topic presented with it.
