Yeah, I’ve never bought a 3rd-party insert or “game chest” thingy that didn’t need to be punched out and glued for assembly. And I’ve got (and am very happy with) a number of such products. (Gloomhaven, Arkham Horror LCG, Mansions of Madness, and Elder Sign, specifically).
What would be most interesting to me about the Folded Space inserts is that I’m assuming they’re MUCH lighter than the wooden products from Broken Token. My loaded up Mansions of Madness box weighs about 50 pounds I think.
