This Replace icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,500 icons, all in the same style and quality.
It's a logo of two circular arrows which close back in on each other to make a circular design. The arrows are pointing counterclockwise with one head on the upper right and the other on the lower left. In front of each head are two dots before the other arrow starts.
