Oh, sweet geez, they're celebrity trading cards.
PopCardz are pretty much the same thing as baseball cards, except lamer. The front features a photo of one of the "world's hottest stars", like Hayden Panettiere, Ashley Tisdale, or Dylan Sprouse. (If you don't know who these people are, ask the nearest preteen.) On the back are fun facts, like the star's favorite quote or deepest, darkest secret. Special "memorabilia" cards include a piece of clothing actually worn by the star. It's almost like you ripped it right off the celeb yourself!
The one redeeming quality about PopCardz is that, through some sort of point-and-token system, you can make a donation to charity. So, that's nice.
