In the previous fan news for Despicable Me Source, I referred briefly to the various types of packaging used for the Minions Blu-Ray/DVD/Digital combo packs (and there are several), each featuring a slightly different arrangement of Bob, Kevin and Stuart, other minions, or just Bob, Stuart or Kevin by themselves with a quote from them.  The variety of packaging, however, doesn't affect the contents, which are the same.  The DVD package does not have this variety of designing, as far as I can tell.

However, as with so many other movie releases recently, Universal jumped into the trend of producing limited edition metal case packaging for their Blu-Ray disks (and the combo packs).  In the case of Minions (no pun intended), the case is shaped like a minion and has Stuart's image on it (front and back).  Stuart appears holding a daisy and wearing a tie-dye shirt, very typical of the setting of the large majority of the movie story (1968).  The front is seen above.  And, below, the back:

These things are usually sold with the purpose of becoming collectibles.  I have a few from different movies, but since they are not usually in the traditional rectangular packaging (the metal case for the Jurassic World Blu-Ray combo pack being a classic example, as it is round), I tend to limit such purchases myself.  Still, once an eye-catching or quirky one, like the Minions metal combo pack, comes out, I make an exception.  XD
