the spell books in my set are pretty poor which is a shame considering how well they are designed in terms of art.  i'm just guessing poor manufacturing.

the blow dryer thing didn't really help but, it's not a huge deal for me.  as long as they hold the cards, sort of help with the immersion of the game world, i'm ok with it.

another suggestion would be a slot or two on the inside covers for me to put additional cards w/ personal info on them.  i made a "wizard" card w/ my tag on it just to personalize it a little more - just spent a few minutes.  (i'm going to make it a lot better when i have more time.)
