I'm so grateful for these rollers. The snaps are perfect and they are the same diameter as the regular heatless curling rod. I use a few of these on the back/top portion of my hair when using the heatless curling rod with the rest of the hair. I'm able to link them in top of my head so I can easily sleep in them. I use the same technique as the rod to wrap hair around and secure with a thin satin scrunchie. The curls come out just like the curls in the rod and my hair looks fabulous!! (I also use the jumbo flexi rods in the same way when using the X-large heatless rod with similar results, just larger curls). Also if you have short hair, using that method with several of these (may need 2 boxes) would produce fabulous curls for those whose hair doesn't reach the heatless rod.
Love, love, love my Kitsch items, especially the shampoo and conditioner bars. I use/rotate every set except the purple biotin and sensitive and can't believe how fabulous the results have been. I'm 44 and I finally have hair so healthy it holds a curl for 2 days, and sometimes even into the 3rd day!!! I no longer need mousse and 2 separate gels to achieve lasting curls. Also works great with a light mist of the new leave-in conditioner!! Thank you, Kitsch!!
