I used a box of these for a year and bought another one for my son. They are cool! There are two sizes and one or the other fits every shirt I have. Being metal, thinner posts are always strong enough that you don't need different widths. I threw away my box of hundreds of plastic holders that come with shirts, all mismatched and deformed. This is such a great product you'll wonder why not everyone gets it. Note that sometimes the corset will pop out of the collar when you take your shirt off and you'll likely hear it fall to the floor. It's okay, but they seem to be more agile due to their weight.
