Rows of plastic tips 30 are provided around the circumference of the foam robber member extending along the length 24 of the foam rubber member. The tips are located at an angle with the horizontal a in FIG. 1 around the circumference. The foam rubber member 20 with the rows of plastic tips 30 in place is placed in a cap 40 made of heat conductive material such as aluminum or aluminum alloy having a body portion 41 and an opening 42 at one side 44 to receive the foam rubber member with the roles of plastic tips having suffecient resiliency to receive the foam rubber member with the roles of plastic tips and maintain them in place.

Abstract: A microwave heatable hair curler comprised of a pair of rigid, hollow, concentric cylinders sealed at both ends to create an annular space therebetween, with a heat absorbant material contained in this annular space. The gel is capable of being heated in a microwave oven to a hair curling temperature and capable of maintaining such temperature for a time sufficient for hair curling to take place. The gel contains a biocide so that it can be permanently sealed in the curler.
