Great deal on metal collars. I've bought some branded rooms like this one and it cost over $40 for 12 stays. I particularly like the combination of this product with the neodymium magnets that allow you to position and hold the collar in place without having to use a button down collar. For events where I need to wear a collared shirt without a tie, I love this product for taming a collar that just won't stay where I want it. I found the 2.5 inch size to be perfect for most of my shirts so I stocked up and bought 4 packs of these as they seem to disappear quite often. I am a saleswoman by profession and depend on a professional appearance and that works absolutely. for a professional collar.
