The key words: “Mirror-like,” which means not a mirror at all, and “travels in a mailing tube.” So you can bring it along on your first date. This was the 70s, after all: you’d  meet someone at the fern bar, go home, get the funky portable mirror out of the back of your van, put it up with double-sided tape,  love the one you’re with, and let her check your back for problem moles. Bonus fun points if you were both completely pounded on Moroccan hashish, looking up, and the thing detached and floated down.
