It’s a vector pack of stickers – colorful and poppy, in a typical Web 2.0 style released by vibr8bros. They come in 2 versions, each in 10 different colors. You can use them for anything you like.
The colorful bam-boom-bang style is still live and prospering. These stickers (or badges, whatever you’d like to call them) can provide a typical Web++ look for your website or blog – if you use them with moderation, and in style. You can write stuff inside, too.
