Abstract: This relates to a fingernail polish cartridge and dispenser. This will be provided as a sealed unit which may be readily placed in a reusable handpiece and wherein there is associated with a cartridge containing the polish a brush attachment and a plunger. When the brush attachment is moved into the cartridge by way of the handpiece, it will automatically open one end of the cartridge, that end being closed by a separately formed plug which has a sealed fit therein. Then a plunger is utilized to displace a removable panel at the opposite end of the cartidge followed by that removable panel seating on a piston and being moved into the cartridge by further movement of the plunger so as to force the liquid nail polish into the brush attachment.
