Beautiful curls with combo of foam & steam. Perfect for “set” curls. Easy to use . Steam, wrap hair around foam and pop on cover to hold in place - yes kinda “ole fashioned” but nice defined curl without the modern appliance damage to hair (perfect for children’s hair too) Total of 30 rollers -6 Jumbo (1 3/4 in), 6 Large (1.5 in), 6 Medium (1 in), 6 Small (3/4 in), 6 Petite (1/2 in). Very clean - only used 1 time. smoke free home. Extra Medium, Small and Petite roller cover I'm a hairdresser that is getting posting a lot of items I have had at Salon. All work great but have done hair for 40 years. Thanks for looking
