my custom icon set, twotone, is now 100% free. every icon in the set, every colour, and the PSD to change the colours to whichever custom colour you want. you can use it on your blog, website, application or intranet.
what’s the catch?
there isn’t one. no licencing, no legal, just do whatever you want them. and if you want, post a link the comments if you do use them on a public site, so i can see where they’re being used and how.
