The Tressecret Holly is a Long and curly style ponytail. The ponytail is made of a high grade synthetic fiber called modacrylic fiber. The Holly retains its shape extremely well and will not wrinkle. It has a large clip that grips securely to your natural hair, and the adjustable drawstring allows you to fasten the ponytail to a desired fit. Due to its heat sensitivity, avoid exposure to high temperatures, (240 Degree F or higher). Length: Approximately 20 inches (when straightened out).
