How can you tell the "series" of JP P2s before buying?

[KuchipatchiPod]

So I want to get the various versions of OG P2 tama, but Japan has two different versions. All sellers on ebay don't specify which version it is. Is there a way to know by looking at the packaging or such? Maybe certain shells are certain versions? I know the egg looks different but you can't see the egg when it's still in the packaging and not turned on.

You can easily tell them apart based on the color of the shell as well as the packaging.
