I really only use two sizes of these collar springs and they are enough for what I need. I take them out before I put the shirts in the washing machine. No fading is excluded and all feathers are very flat with no kinks or waves and have a comfortable weight. I suspect most people need a collar size or two at most. Although it was pretty cheap to buy, I'll probably never use half of it. It's probably wiser to just buy the size or sizes you need. Although it is very beautiful.
