So, I still haven't opened up my platinum founders pack, my question is when you open the pack out of the "product inventory", does the exclusive skin automatically bind to that character?

Can you sell it on the AH, or is the skin tradeable?

Any feedback is appreciated. Thanks.

You'll get individual packs as listed on the founder pack.

The mount/skins are sellable.

So, the skin itself will be in an individual pack? Is that pack tradeable/sellable?

These are the skins I'm referring to:

Yes.
