Review (5/5): what I needed.
I got these for putting my hair half up. It is thin and wavy. They worked perfectly for this. It is a little difficult to twist them in order to wrap them twice. I was able to get 2 fingers in to do this. I took a picture next to a dime for reference. They are about the size of a dime. They do not have as much stretch as the regular ones. I would definitely only recommend for styling small chunks of hair.
