A miniature dispenser for dispensing fluid materials such as liquids or powders. The dispenser has a body which contains a piston and a material reservoir which is separable from the body and contains the fluid material. The material reservoir includes the passages, valves, and nozzles through which the material being dispensed flows and also includes an integral collapsible material container. A user may assemble the body to different material reservoirs and each material reservoir may be tailored to the properties of the material it contains. The dispenser is small enough to be worn as part of a bracelet or to be dipped to a pocket, belt, backpack, or purse.
