These are, to me, a complete innovation in lip colour. The formula is liquid, much more runny than your average lip gloss, and yet the colours are the most opaque i've ever used. You only need a tiny, tiny bit of the tar to cover your whole lips. They come in a fantastic range of colours, including an amazing blue, orange and purple as well as a lot more 'conventional' lip colours and because they're liquid they are made to mix together and create your own custome colours!Full review and swatches of the colours i have on my blog:http://lillianfunnyface.blogspot.com/2010/01/obsessive-compulsive-cosmet...
