I'm going to be donating rather soon, and I want to know about a few of the items but no matter how hard I look I can't find any really useful information on them.

For the June Collection, do you only get one of those items or all of them?

And for the Mysterious Costume Trunk, do you get to pick which costume box you get, or is it random?

Collection: You get one, but you can choose which one.

Costume Trunk: You can choose, out of the available ones (not the retired ones)

Alright, as long as you can choose I'm fine with that. I dislike the random factor. Thank you very much.
