Those palettes are fake, as are most of the MAC products on eBay. MAC palettes generally hold 4 or 15 pans of shadow (and are customizable) with the exception of limited edition items from special collections. Even then, they never have as many as 120 colors. If it’s not listed on the regular MAC or MAC pro site, I’d say it doesn’t exist.
If you’re friend is looking for a palette with many colors to get started, I’ve heard that these are quite good: http://www.coastalscents.com/cfwebstore/index.cfm?fuseaction=category.display&category_id=122 It’s not MAC, but it’s an affordable way to learn make-up or build up the range of colors in your collection quickly and cheaply.
