It's a logo of a key changing hands. One hand extends from the right on bottom with its palm facing up. The other hand extends from the left on top and is dropping a key into the other hand.
This Lease 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 15,800 icons, all in the same style and quality.
