This ISO 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 15,300 icons, all in the same style and quality.
The logo is a rounded rectangle that is longer horizontally than it is vertically. On the inside of the rectangle are the letters "ISO" in all capital letters. The letters are centered on the inside off the rounded rectangle.
