The secret to Caruso Steam Hairsetters is in the setting rollers. Available in 5 sizes for maximum styling versatility. 6-rollers pack each size. The patented roller design allows for breathing space between the foam and the shield so steam evaporates faster and curls set tighter. The unique shield lock holds rollers tightly and end caps have slots to hold clips when needed. The Molecular roller foam (also called sponge curlers) holds steam to give you the most curling power. Available in 5 roller sizes for maximum styling versatility: * Small: For tight curl, short hair and spiral curls. * Medium: For medium curls, medium to short hair or medium to fine hair. * Large: For looser curl, volume and body. (May be referred to as "Jumbo Large" in packaging.) * Jumbo: For largest curls and waves, long or thick hair.
