I don't really have much to add as all my collars have been plastic so far, whether removable or sewn/sewn into the collar. (Such a closed life I lead, don't I?) But I gotta tell y'all, these things hold good weight and be looked at. I can't wait to try them out later this week when I get back to work, but for now I'm giving them 4 stars for the reasons stated. Update pending.
