I'm guessing that the 880 has the same "Barbie closet" that the 820 does?
I have never used it, and like the others have a plastic divider case.
Also with the movable dividers to allow for off shapes/sizes, and marked as to which machine (three).
Right now, I have enough extra spaces that I keep my sewing machine needle stash in there too.
That'll only be until more feet are added and then they will move to their own box.
