Urban Decay Nirvana Build Your Own Palette Limited Edition Holds 4 shades. Just pop any four UD shadows out of their cases and into this customizable palette. This limited-edition design is only available for a short time. The dripping purple artwork on the case has a lot of depth and texture- it almost looks like makeup. Lift the lid to reveal a gorgeous transparent purple interior and full-size mirror for on-the-go touch-ups.
