These Classic Styler Rollers by Hairware are not only the most durable rollers but they will last much longer than the other cheaper copy cats around. They are 50% lighter than those old fashioned rollers we use to have to endure decades ago, the ones that bothered you all night and kept you from getting any sleep! They are perfect for both perms and sets with their hundreds of tiny little holes to help your hair dry faster. They can also be sterilized! Hairware Classic rollers are easy to remove without snagging or tearing out your hair tangling and are wonderful to use while blow drying to add bigger volume. They are self-gripping so no pins or clips are required. Can be used on wet or dry hair for sets or perms.
