WebAppers has released a set of Web Application Icons a week ago. And now, Monofactor has released a set of 25 Vector Icons for Free as well. They look really stunning. And the loveliest part is, they are in scalable vector format. You can open the .ai file with any version of Illustrator above 8.0. With earlier versions, you might loose some of the effects on the icons.

Redistribution, Release for Download or Selling of these icons on an another site without permission is completely prohibited. However, you are completely free to edit, change and/or directly use the icons in your site and in any kind of your projects.

Requirements: Illustrator 8.0+
