Is there a reason for...

selling something that you assume you can do with it what you think it's there for? I bought these at a hobby store and shoot you can't put anything in the middle of them!! I assume that's what they are for since they have 2 pieces of glass with them. I made a collage of paper, it wouldn't close, so I did this and it still wouldn't close and when it did this is what happened! But I could see it as fate, because of what the words say and it "broke".
