Alright, this may seem like a silly question, but bear with me. Is there any special type of adhesive for cardboard, or will regular paper glue work just fine? I ask, because my Lunar: SSSC box has a flap that popped open on the front, and I have to glue it back. Thanks.

(I tried searching, but as you can imagine, "cardboard" and even "glue" show up a lot on this message board.)
