I recently opened a box of 2007 UD Elements on my blog as part of a group break and I noticed that the product wasn't represented here. Each box comes with 3 mini boxes - each box featuring a different technology if you will.
I chose a pack out of the Derek Jeter box since the cards are printed on clear acetate plastic. At only 3 cards per pack this will be a very short post!
If you're a stats person then you won't be all too pleased with the backs.

It appears that each mini box yields one numbered RC in additional to some sort of hit.
