Maybe I'm slow, but...
I just figured out why the plastic face spacer comes wrapped in those little soft fabric sock things. It seemed overly elaborate for shipping packaging, just to protect the spacer... until I realised it's to allow the spacer to be used as a magnetic snap on lens cover when the Frame is in storage.
I figured I'd mention it, because I've seen several reviewers throw the socks away, and I haven't found any official instructions that mention this. Unless it really is just packaging, but it's awfully convenient!
