Material and comfort These sponge curlers use a soft sponge core with flexible ABS bars. The combination is soft, durable, and comfortable to wear, enabling longterm use without causing discomfort. Easy to use No separate combs or clips are needed. Wrap the hair around the roller, open the straps, secure with the straps, and you can sleep while your hair sets. In the morning, you wake up with curlready hair. Moisture management and drying The flexible ABS bars won't snap or break as you roll the hair. The design is heat and the absorbent bars help pull moisture from the hair as it dries, supporting quicker drying and helping set the curl.
