This icon has two three dimensional boxes that are sitting on top of each other. A long slanted, horizontal line is going through the middle of both of the boxes.
This Do Not 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 15,900 icons, all in the same style and quality.
