I reviewed Urban Decay's liquid liner packaging and formula a couple of days ago, so I won't repeat that. Instead, I will show you pretty pictures of this very pretty liner.
It's a vibrant blue-purple with great pigmentation and excellent staying power.
The thin, flexible brush is perfect for a thin line. It retails for $18 but is currently on sale for $7. I bought mine at a HauteLook flash sale at a considerable discount.
