IconShock has designed a set of icons specifically for DesignM.ag readers. The set includes five icons that were created for use in e-commerce websites. The icons are free for personal or commercial use.
The icon pack includes an Adobe Illustrator file and a PNG file for each icon.
If you’re not familiar with IconShock, I recommend taking a look at their site. They have a ton of icons that can be purchased, and they also offer custom icon design if you have specific needs.
