Today, I’m offering you a nice little freebie I’ve been working on lately. It’s my first experiment of this kind, but I am happy with the result and I thought you might find this set useful. It consists of 30 freebie fully-editable duo-tone browser control icons. The paths in the Adobe Illustrator project file are intact therefore fully-editable. You can safely change the colors, sizes, stroke size (by default the icons are 40x40px with 2px strokes).
I hope you may find this useful because of the customizability; I noticed that lots of similar icon sets come as vectors but the paths are expanded (and not editable).
