Well, I opened up one of mine.
The body is a standard Commtech Stormtrooper body that we have hundreds of. Nothing special here. It should have been the votc stormtrooper body for the price we paid for these things. But I digress. The helmet is a very soft rubbery plastic. It looks bigger to my eyes than the regular commtech helmet. The Lucas head itself is pretty well painted. He has lots of body and the neck post is the same as the commtech stormtrooper. It's not a ball post head. So this head isn't really compatible with other figures heads unless it's another commtech stormtrooper.
The package says the Saga Collection on it. The card is a nice vintage stormtrooper card. The case is the typical VTSC case but is taped shut not vacume sealed. The white mailer is simple and says George Lucas (in Stormtrooper Disguise) on the front. I wonder how many postal employees will manage to divert these from their home destinations to ebay.
