These are the real deal! I can't guarantee it but I believe they are all mink, I know both the darker and lighter brown ones are. If the light gray one is not mink, it may be fox? Wish I could tell you for sure. I can guarantee they are all real fur. These all fasten to form a collar or of course you could sew them on to your garment. The darker brown mink measures 26" and is 3" wide, the lighter brown measures 29" long and 3.5" wide. The light colored one is the longest at 38" and 4" wide. These are all vintage if not antique. They are clean, odor free and in good vintage condition.
