  • Hair roller
    Patent number: 4310008
    Abstract: An entirely resilient or "soft" hair roller. Tubular netting surrounds a soft cylindrical member and has soft end tabs that are mutually adherent when juxtaposed in contact with one another. These hair rollers can be worn without discomfort even when the wearer's head is resting on a pillow because they lack rigid or semi-rigid elements that might press against the scalp.
