A selectively removable and protective nail cover kit that includes one or more elastically deformable and unitary bodies each having a sidewall with an outer surface, with a first end enclosing and defining a lower aperture, with a second end opposing the first end of the sidewall, defining a body length separating the first and second ends of the sidewall, of a practical sidewall thickness spanning the body length, and with an inner surface defining a nail placement cavity that is enclosed by the sidewall and preformed into an arcuate shape, spans from the lower aperture and terminating at an upper internal wall of the elastically deformable and unitary body that is disposed proximal to the second end of the sidewall, and of a length less than 2 inches.

The invention is a protective nail cover for use after nail polish application. The nail cover is one piece flexible rubber that has a “squeeze to open” mechanism. It is made of a flexible but firm rubber material that can be applied over each fingertip, extending to the first joint to cover the nail without touching the nail. It will have holes for ventilation around the bulb portion. This bubble nail cover can be squeezed gently at the sides to open. The cover will gently close over the finger and may be lined with some sponge like material to make it more comfortable. The whole purpose of this cover is to protect freshly applied nail polish and allow it to dry.

A fingernail sleeve device for enwrapping both the finger and the elongated decorated fingernail includes an opening. The opening is circular and is coupled to a surface. The surface has a finger side and a nail side and enwraps the end of a finger. The nail side is positioned upon the fingernail of the finger, and the finger side is positioned against the skin. A cavity protrudes out from an end of the surface and has a downward curvature. An elongated decorated fingernail is nested within the cavity. The cavity defines an enclosed space for the fingernail. The cavity and the nail side of the surface have a hard material to protect the fingernail within the fingernail sleeve device. The soft material facilitates the application of the fingernail sleeve device to the finger.

A device for applying a liquid or pulverulent medium is provided. The device includes an application element that has a flexible width and that is attached between two support elements and includes at least one lateral delimiting element for the purposes of a controlled and fast application of this liquid or pulverulent medium. A kit that includes the device and a media container is provided.

A nail polish application system may include a nail polish applicator to apply a curable nail polish to a nail of a user. An energy source may emit energy to selectively cure the curable nail polish. A sensor may be provided to detect a boundary of the nail of the user. The energy source may be configured to direct the energy to (i) the detected boundary of the nail during a first curing stage or (ii) to an area within the detected boundary of the nail during the first curing stage, and to (iii) avoid directing the energy to an area outside the detected boundary of the nail during the first curing stage.

An electric nail filing device includes a cylindrical body having a battery holder attached inside in the body, a cover attached to an open end of the cylindrical body, an on/off switch attached on the cover or the cylindrical body, an electric motor having a metallic rotary filing wheel, and a safety guard cap attached and covering the wheel, shaped like a rectangular prism, a pentagonal prism, a hexagonal prism, or a multiplane prism having multiple planes and a tubular cylindrical housing inner space which has enough space to cover the wheel, in which the safety guard cap has multiple slots on the planes, and an adjustable guard tab attached at closed end of the safety guard cap. Optionally the safety guard cap is covered by a nail debris collector which is shaped like a half-dome covering all other planes of the safety guard cap except one plane.

A polish curing assembly for curing and hardening nail polish includes a stand is that may be rolled along a support surface. A light emitting unit is coupled to the stand and the light emitting unit is positionable above a person's hand whose nails have been polished. The light emitting unit emits electromagnetic radiation when the light emitting unit is turned on to cure polish on the nails.
