If you've never worn metal corsets, welcome to the big league. Just remember to remove them from your shirt before washing. Also, do yourself a favor and buy some magnets if you ever wear a shirt without a tie. If you've had metal collars before, you probably only care about two things: are they strong/thick enough and are they the wrong size for certain shirts? . They're definitely thick enough, not too thick to feel heavy, but not too thin to bend or feel cheap. They are sized long enough so they don't bag and the width is perfect so they aren't too wide and straining, and not too narrow so they don't fall out when trying to wear them.
