Fripac Self-Grip Rollers 12-pack 44 mm pink. The aluminum core of the Fripac self-grip rollers retains heat, allowing hair to dry faster while providing curls with more bounce and longer hold. The plastic body for insulation gives the Fripac self-grip rollers stability and protects against direct contact with the hot aluminum core. A special adhesive tape securely holds the hair on the roller without the need for pins, clips, or rubber bands. Available in various colors and sizes. The bag contains 12 pieces.
