Can you be a little more specific? Messed up how? Zine spines are known to be rather flimsy (especially thicker ones like TAT), but I’m not quite sure what you mean.
They were very frayed. Like the paper itself was broken along the fold line of the spine when they were pressed and doesn't seem like it will stand many openings/closings before breaking off. I understand that zine spines are somewhat flimsy, but I own quite a few modules and this is the only one I've seen with this issue (twice), so wanted to give a heads up.
