This icon is made of 3 rectangles stacked on top of each other like you might stack books on a shelf. Each rectangle has a small black dot in the right corner. The icon is meant to represent things stacked on top of each other.
This Stack 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 16,000 icons, all in the same style and quality.
