This Navigation Toolbar Left 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.
The navigation toolbar left is a rectangle shape and inside the rectangle it is divided in two sides. On the left side of the rectangle there will be other buttons or selections, which are represented by tiny circles or rectangles.
