Set large, voluminous curls with the Annie Cold Wave Rods — salon-grade jumbo perm rods built for all hair types, with a curved design and flow-thru vents that ensure even saturation and consistent, long-lasting results at home or in the salon. Rubber band holds hair securely in place around the rod throughout the entire setting process. Large curved perm rod shape creates full, voluminous curls with natural-looking body. Small ridges and textured surface grip hair firmly to prevent slipping during use. Flow-thru vents allow for better solution or moisture saturation from root to tip. Narrows in the center to create a tighter, more defined curl at the root for lasting results.
