I would normally use plastic collar holders that button a shirt but if I accidentally leave them in the washing machine from time to time they will deform. Also, when I took my shirts to the dry cleaner, they mysteriously disappeared. I got tired of not having enough or the right length and decided to buy them. It was worth the price, the different sizes make it easy to find the right length and the metal makes it strong so it won't warp. The case is comfortable but my only complaint is that there is no easier way to find different sizes than turning it upside down, but for such a small issue this product is worth the price.
