Review (3/5): They are cute, and kind of fun to have, but not for serious curling.
They are big, for some reason I thought they would be about the size of a golf ball, they are more like the size of a tennis ball. They are soft so laying on them over night is fine however some fell out and none of them really gave me any real sort of curl, partially because I had to pull and yank my hair out of them. The material sticks to the hair and tangles it all up. Because they are so bulky I think I wasn't able to really wind my hair tight enough to prompt a good curl. They look super cute in the basket in my bathroom and I took some silly pictures with them in my hair but not worth using them again.
