i just wanted to know if you can pick which item you want when you open it and how many :D thanks

When you open a donation present, the item you receive is random; you don't get to pick. You will only get one item per present. :)

If it's called a Donation Present, then no, you get one random item.

But if it's called a Collection you get to choose one item that you want. :)

Denzel already said.

ok thank you ~ that was very helpful
