Methods, kits and structures are disclosed for providing a desired protective and/or visual effect to natural or artificial nails. One method comprises applying a base coat to at least part of an outer surface of the nail substrate; providing a flexible support having disposed, on a surface thereof, a monolayer of metallic-looking particles of at least one metallic-looking pigment; and transferring the monolayer from the flexible support to an outer surface of the applied base coat, so as to form a coat of metallic looking particles on the nail substrate.

An symmetric-multi-function-concave-operating-edge symmetric-multi-function-operating-tip artificial nail, for being glued to a nail of a finger or a toe, comprising: a base, at least two base edges molded to the base partially along the base perimeter, an extension molded to the base partially along the base perimeter and the extension perimeter, at least two concave operating edges molded to the extension partially along the extension perimeter, and at least two digital-and-mini-icon-and-keyboard-operating tips molded to the ends of the at least two concave operating edges respectively. The at least two concave operating edges are for efficiently being narrow and flexible to provide efficient grips on objects, to absorb vibrations to protect the nerve system of a finger or a toe, and to efficiently apply, spread, and shape lipstick and lip gloss on lips. The at least two digital-and-mini-icon-and-keyboard-operating tips are: for vertically, horizontally, or angledly touching, pushing, striking, activating, or operating multiple digital keys at the same time on a digital keyboard; for vertically, horizontally, or angledly touching, pushing, striking, activating, or operating multiple keys at the same time on a mini keyboard; for efficiently functioning as comb teeth to comb eyelashes and wet or clumping-together eyelashes.
