Abstract
Abstract The nail form device of the present invention comprises an integral structure having a forward portion and a rearward portion. The forward portion has an upwardly convex surface for supporting the synthetic nail which is to be attached to the natural nail. The rearward portion has a downwardly concave surface for supporting the finger to which the synthetic nail is to be attached. An opening is positioned in the upper portion of the structure and has a forward edge formed by the forward portion and a rearward edge formed by the rearward portion. The opening is adapted to receive the forward portion of a finger with the forward edge of the opening being adapted to insert beneath a portion of the natural nail. The forward portion gradually tapers to smaller dimensions away from the opening, and provides a removable support for the nail extension. The rearward portion is shaped to hold at least the under portion of the forward portion of the finger and cooperates with the opening to position and hold the natural nail for application of the synthetic nail.
