Described are articles that serve as integrated dispensers or applicators for powdered compositions. Primarily, the powder-dispensing articles of the invention include a housing in which a cartridge is disposed that can move in relation to the housing, typically by depressing a plunger that protrudes from the housing. The housing unit contains a housing access port that provides access to the preferably replaceable cartridge. The cartridge also contains an orifice, referred to as a cartridge access port, in the cartridge wall. The housing and cartridge access ports are brought into alignment by the user, for example, by depressing a plunger that causes the cartridge to move in relation to the housing by compressing a biasing member. Such port alignment exposes the powdered composition inside the cartridge.
