Unidentified Collectible - .hack//SIGN

[tubsiwub]

Hey guys, I'm new to the site and this is obviously a fresh account... but I'd like some help identifying this .hack item I have if possible.

When I acquired it, I was told that it was a box given out to employees at Bandai as a sort of preview advertisement set for the press. As cool as that sounds, I can't find information about this anywhere online and it would be cool if someone knew what it was (if not what I was told), or if someone could confirm this information.

Below are some photos of the box + contents:

Top lid, front cover
Back of box, underside
Opened, full view
Close-up of advertisement
Contents sans-plushie

As always, please let me know if I'm breaking any rules or if I'm in the wrong forum for this kind of thing. Thanks in advance!

I did respond of Discord, Bandai released a promo box for SIGN and LotT which have the first volume and extras such as a demo,poster,shirt and plush. Like most people I'd never even seen them but managed to get both from ebay though who knows when another will appear again,pretty sure Erroneous linked my initial post of the SIGN box in the "What is Your Rarest .hack item" thread ^_^
