They are all promotional items, the cape and mite plush are from the Comic-con when you pre-ordered the game from there you got both of these things for free.

The cursed drippy plush is an other promotional item, from what i've seen you can only obtain it from winning in contests and such, it's quite hard to obtain.

The small drippy plush could've been obtained here from different shops when you ordered the game from a specific shop.

The book is just a Japanese Wizard Companion guide most likely which can be seen a lot on Ebay everywhere, that one isn't so rare at all.

So yeah, it isn't worth the 700 dollars at all because you mostly pay for the Mite and cursed drippy plush + the cape, the other things can be seen a lot on Ebay from what i've seen.

But there are more promotional items though, such as the huge drippy plush, that one you might not ever see on Ebay, because it's extremely rare.
