Theres not much to a collar stay. There are 3 sizes and are all the same width. My only complaint is that I dont have any shirts requiring the short ones and sometimes I need some that are double wide. Either way a good value if you go through collar stays like I do. 7/21/15 Update: Well I am still using these same stays. Some get lost I think I only have the smalls left but they have served me well.
