Abstract: A device for applying or removing nail polish or nail art has a replaceable cartridge with a distal end removably coupleable to a proximal end of a handle. The cartridge has a reservoir that contains a liquid, such as nail polish or nail polish remover and a flow control member (e.g., valve) actuatable to allow flow of the liquid out of the distal end of the cartridge. The handle has a flow path therethrough that extends between its proximal end to an applicator implement (e.g., brush, sponge) attached to its distal end, the flow path in fluid communication with the flow control member when the cartridge is coupled to the handle. Selective actuation of the flow control member by the user (e.g., by squeezing the cartridge) allows fluid to flow out the reservoir and through the flow path in the handle to the applicator implement for application of the fluid by the user to a finger or toe nail.
