>>10361528For those poster POPs like in the OP, Funko glued and/or screwed it on and the poster on the back is held in place with a screw (there is a hole in it). The POP figurine is also held down to the base, usually with a screw.
I just found out opening a Killer Klowns POP and was pretty upset to find that out. I had to shatter the plastic shell to access the poster. The figurine itself was glued to the base basically. Also it molded to have it fastened to the plastic shell for some dumb reason. It is hard to explain. Ultimately Funko designed them to not be removable from the plastic shell, just as display items like that. I wanted OP to know just in case he didn't know.
