Did a little Googling. Icebox was from their 2000 Merry MAC-Mas collection. http://www.temptalia.com/mac-cosmetics-merry-mac-mas-collection-for-holiday-2000 Pretty Twisted was in the Dolled Up collection from spring 2002, but it seems like it was in the permanent line for a while but discontinued? http://www.temptalia.com/mac-cosmetics-dolled-up-collection-for-spring-2002
