This is our first responsive icon pack. Each icon was created in four different sizes with different level of detail. First, each icon has a small and large version (just like on the Microsoft Office toolbar, Office ribbon): 16x16, 30x30px. Second, each icon has the low-res and HD version(40x40, 80x80). This results in four sizes, each of which is a separate drawing created manually.
This icon pack fits any application in Microsoft Office style.
