Review (5/5): Work well!
For a heatkess curler these work very well. I put my wet hair into them after a shower and slept with them on. As long as you do smaller sections of hair it will dry over night and be fine in the morning. I didn't even need hairspray and my hair never holds curls. I'm sure if you don't want to wear them over night you could use the hair dryer to dry them and it would work just fine.
Not comfortable to sleep in but beauty isn't always comfortable right?
