This Original Size 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 icon is a rounded horizontal rectangle. On this card is inscribed "1:1", as tall as two thirds of the rectangle's height, representing a zoom ratio indicative of the icon's original size. The icon represents setting the zoom level to the original level.
