Turns out if you put sleeves on your out of print card game it doesn't fit in the original insert.

Sleeves shown are Matte Orange Standard Size Dragon Shields, this should work with most single-sleeve options. Other sleeves might not be exactly level with the top of the hero card holder, so if you care about your manual getting scuffed keep that in mind.

My print was a bit tight on the Weakness pile, so I added .1 millimeter to the final internal size of the buy stacks. It's not enough of an issue for me to reprint mine, but seemed prudent. It's a little loose in the box, but I'm not sure if that's wear on my box, measurement error on the part of the person who designed the insert I based the exterior dimensions off of, or some combination of the two.

Does this work for other Cryptozoic games? I have no idea, I don't own any other ones. If I end up getting the Street Fighter one I'll check.
