To provide convenience if only a part of a nail has something to reflect when especially, a lipstick sometimes needs to be re-applied since women are always conscious of makeup on a face though people have fun for beauty in applying manicure on the nails of hands or recently variously performing art on the nails.

A mirror is stuck on the nail of the thumb of a hand. This enables a person to clearly view a part of his/her face on looking in the mirror on the nail when the thumb is held up. Besides, a person can see backward on looking in the mirror with the hand placed by the side of the face.
