Great lip pencil! I love Urban Decay's eye and lip pencils because they go one really smooth with little effort. It is Def a great buy! Also they are waterproof which is great for long lasting color.
I use Gash under every red lip I do on people. The fact these super creamy, yet waterproof make them perfect bases underneath any lipstick color! Instead of just outlining the lip with color, I fill the entire lip in so even if the lipstick wears away, there is still the lipliner underneath!
