This "set of sets" is one of the limited edition products made available as part of Sephora's 10-year anniversary celebration.

Aside from being a good offer, I think it's a great idea to get these and use some as stocking stuffers at at Christmas, or as daily gifts for the Secret Santa that is played in many offices during the Holiday Season. Like all Too Faced makeup, they include gorgeous colors and have lovely packaging - any gal would be happy to get one... or several!
