A must have for overnight mermaid waves! With super long straight hair that doesn't hold a curl, or a wave usually, these are like a magical solution for me! I like how super duper easy peezy they are to use and I can actually sleep with them! For reals! I just wish I had discovered them sooner! I would've saved so many frustrating, I give up-my hair will never do anything moments of total frustration and disappointment! They work you guys! I wrap my just damp hair around them, bend them to secure and that's it! A night of sleep and I literally wake up with the smooth, shiny princess hair I have admired on all you ladies my whole life! So inexpensive and free of any possible damaging effects........ absolutely worth a try! Big Loves and Sparkles✨! I even capitalized that !!!
