I finally found the right curler!
I cannot guarantee this curler will work for everyone, because apparently we are supposed to measure the curvature of our eyes in order to find the right one. I didn't do that, but I did take the suggestion of someone who has very similar facial structure to me, and she was right.  This was the one.  I also learned to hold the curler facing inward (I don't know how to describe it--watch youtuber fabulous50s to see it) and my lashes look amazing.  Great buy!
