Designed for sculpting nails of any length and shape, the DARK extended lower nail forms give the technician a solid foundation for building precise nail architecture and simplify the entire extension process. The rigid structure of the forms holds the correct arch throughout the work, preventing the material from sagging or losing shape. A strong adhesive base keeps the form securely attached to the finger without shifting or peeling off, while the markings on the "wings" allow quick, accurate trimming around the sidewalls for a more anatomical, comfortable fit.
