Hair curling rolls of cellular polyurethane or similar material - can be skewered at any point and are easy to mfr. and use

摘要

A hair curler comprises a solid or hollow cylindrical body made of a material which can be pierced at any point by a small pin or skewer. The body may be of rigid or semi-rigid material, specifically of a porous plastic material such as polyurethane foam. It is simpler to make than fabric rollers with spring supports or ribbed hollow mouldings, and can be more readily fixed to any position among a person's hair.
