Abstract
A non-electric hair roller device is utilized with a plurality of generally cylindrical heat conductive rollers of different diameters as a curling iron or hair setter. The hair roller device is non-conductive and includes at least one support leg which is pivotable and compressible with respect to the rod portion of the device and the stack-up height of the support leg and the rod portion is greater than the inside diameter of the largest conductive roller to assure that the roller is retained on the hair roller device even in a roller down orientation.
