It's a 4-shadow set with a trial size of the eyeliner in Zero!
Called Urban Obsessions, the shadows are about the size of nickels, and the colors are Skimp (matte yellow-cream), Bust (satin dark neutral), Guilt (shimmer soft pink), and Oil Slick (sparkly black). Two are supposed to be exclusive colors - thinking it's Skimp and Guilt.
Anyhoos, I was at Sephora today and the awesome lady at the counter asked if I wanted to redeem any points, and I commented that I was waiting for Benefit, Urban Decay, or Make Up For Ever to have the 500 point sets. She asked me to wait a minute, and came back with the new insider reward and asked if I wanted it (OF COURSE I SAID YES!).
