Nice set. The sizes are standard and fit each of my shirts in both length and width. A pack of 60 is a lot! I can't imagine ever needing that many, but it's great to always have a few extra for life. The only downside I see is that they are a lot thinner than the plastic collar posts that come with the shirt itself. Thinner yes, but not thin. They still do their job and make a nice emergency/temporary fix.
