You may underestimate the need for collar halters until you see the difference in wearing a blazer. I tend to always lose the ones that come with the shirt, so not only does this product provide a backup of lost stats, but the magnets allow for perfect positioning of the collar. Be careful, magnets can easily get lost when you undress or put on a tie if you forget you're wearing it. I keep these in my laptop bag so I always have them to hand.
