In 2016, Urban Decay celebrated their 20th anniversary with the release of their XX Vintage collection. They re-released 12 of their original nail polish shades (Asphyxia, Bruise, Frostbite, Mildew, Oil Slick, Pallor, Plague, Radium, Roach, Smog, UV-B and Uzi). When I purchased this collection, Asphyxia was out-of-stock. Luckily, I just bought Asphyxia off of eBay!
