This is a 4-in-1 dual form. In addition to its standard features—convenient shaping and clear scale lines—its greatest innovation lies in its multifunctionality.
The set includes 15 sizes: A, B, C, and 0–11.
Sizes A, B, and C are specially designed for toe nail extensions.
Sizes 0–11 are intended for fingernails.
Moreover, the dual form is double-ended:
One end is designed for full coverage application (full-stick mode),
The other end supports a half-coverage application (half-stick mode).
