Abstract: There is disclosed herein a fingernail reinforcement extension material. The material is formed of a woven fiberglass fabric having a vertical and horizontal cross-thread count in the range of 25 to 55 threads per inch. Impregnated within said fabric is a preparation including cellulose, nylon fiber, resin, plasticizer and solvent in which, upon evaporation of the solvent, the preparation forms a hardened matrix within the weave of the fiberglass fabric.Also disclosed is a method for the use of the material in order to accomplish the reinforcement and extension of human fingernails.There is disclosed herein a fingernail covering for reinforcement of nails. The nail covering is formed of a woven fiberglass having a vertical and horizontal cross-thread count in the range of 25 to 55 threads per inch.
