It's interesting, mine don't fit on the kallax from ikea, but they do fit on the cube from places like walmart and target. So that's what I did. I have my main shelves and then an independent shelf for dark horse, image, and oni, all of them fit there just fine. - Cheers!
There are ways to add that extra mm of space you need to fit those in a Kallax.. But it’s definitely easier to do it while you’re putting it together initially.
Hey, I think your kallax shelf is is erected on the wrong side. You should flip it 90 degrees, that way the long shelves in the middle take the weight of the books. I noticed some of yours are sagging because you have the short shelves holding the books.
