Difference in Corkscrews!

So I just bought a six pack of the corkscrew nose rings, and after fighting with trying to get them in(never got them in), I noticed that two of the six turn an opposite direction. Why is that? How do I know which to use? Does it even make a difference?

As you can see in the picture, one is going to the left, and the other is going to the right. There is even a difference in the bend.
