When my binder is fully zipped up, there is a protruding end on the zipper itself. Not to be vulgar, but it looks like a little weiner on the end of the zipper. I assume I got one that was made incorrectly. When I emailed about it, I never received a response. I otherwise love the binder. But that little defect is stopping me from buying any more. I would buy more. But I need to know they all do not have this defect before buying. Please email me.
