[QUESTION] CD + DVD single cases...?

[Chiharo]

Okay, so I hope that this is the right thread to post this questions since it's not related to Ayu so I couldn't post it in enquiries forum.

I have a question about what is the case like to CD + DVD singles? I've just got Nana Tanimura's CD + DVD version of every-body (which is my first single ever) and I've never seen it because it's in my friend's possesion now (I'm going to receive it soon). Right, so I always thought that with CD + DVD singles you get the double case just like in any CD + DVD album, but my friend has told me that it's just one case (like any normal CD only album).

This confused me since I saw all other CD + DVD singles (when people were taking pics of them) having double cases for them.

P.S. It's also possible that my copy of single is first press, but I'm not sure since they got it from amazon.co.jp.

Thanks in advance.
