A single-use applicator contains nail polish remover and an applicator element. A liquid conduit has one end fluidically connected to the applicator element and a point on another end. The nail polish remover is liquid and is contained in a container having a puncturable cover that is located adjacent to the point of the conduit. The applicator element is located in one unit and the liquid is located in a second unit. The two units are threadably connected and when screwed together, the point punctures the cover and fluidically connects the liquid nail polish remover to the applicator element. The applicator is used in the manner of a writing instrument to remove nail polish.
