Fripac Self-Grip Rollers 12-pack 32 mm yellow. The aluminum core of the Fripac self-grip rollers retains heat, allowing hair to dry faster and giving curls more bounce and longer hold. The plastic body provides insulation, ensuring stability and protecting against direct contact with the hot aluminum core. A special grip tape securely holds the hair in place on the roller, without the need for pins, clips, or rubber bands. Available in various colors and sizes. The bag contains 12 pieces.
