Viva Glam VI Special Edition is a limited edition lipglass that is a part of the 'Viva Glam Line'. That means every cent goes to the MAC AIDS Fund to help people with and affected by AIDS and HIV. The color design was helped by Fergie and meant to be an alternative lipglass to be worn with the Viva Glam Lipsticks other than the current ones (Viva Glam V Lipglass, and Viva Glam VI Lipglass). Right now availability depends on how much a store/counter still has. The stock will not be replenished until next spring (2009) when it will be repromoted again with Fergie. Hope that helps.
I personally love the color. A nudey mauve. Great alone or with any lipstick.
