This 4k 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.
This is a square, with the top and bottom lined with several smaller squares. The characters "4K" are in the middle of the big square. There are eight squares that align both the top and bottom of the big square.
