The flag icons are super nice.

As for the "littlebox icon set", from my standpoint (mostly designer) no. In an icon set I am looking for a) feel and b) perfect balance between each icon so everything feels connected.

That in itself is super hard to get right, even when not limiting yourself to CSS to do it. While this is an impressive feat it doesn't get there for me on either front, compared to what's available out there. So unless there was a very specific reason not to resort to an actual font and/or graphics, I wouldn't consider this one.

Brazil's flag looks really weird. I would say it's unusable...
