Abstract
A dispenser for magnetizable articles such as pins or paper clips. The dispenser has inner and outer concentric, slotted cylinders, the first cylinder being rotatable within the outer cylinder for dispensing articles through the slots. A pair of spaced magnets establishes a magnetic field which intersects the path of the dispensed articles for suspending the articles in the field without the aid of mechanical supports.
