Actually worked!
Worked great on daughters thick hair. Easy to use. Only took about 10 min to do her whole head.  I bought two packs thinking one wouldn’t be enough, but I only used 1 from 2nd pack. The piece used to pull through kept falling apart and needed snapped back together. But I still managed to do it in 10 min. She said they were a little weird to sleep in. The curl held two days.
