Do you remember them?? I vaguely recognize the photo, but I’m pretty sure that I have never used them. According to Beanie over at Advantage Style, “These Hair Spools Are Pinless and Pliable.
Unlike conventional hair rollers, which are hard and unforgiving, these tried-and-true hair spools are made of soft, pliable plastic so you can leave them in overnight and still get a good night’s sleep.”
The most “ouchless” rollers I remember were pink foam with plastic snaps that “snapped into place to keep the roller in place. While they certainly were easy to sleep in, they did leave a dent in your hair. Not pretty!
