A stapler is stacked on top of a roll-type tape dispenser. The tape dispenser top surface and the stapler base bottom surface have complemental three dimensional contours which cause the tape dispenser and stapler longitudinal axes to be in parallel relationship when the surfaces are in abutment, prevent relative displacement of the tape dispenser and the stapler when they are stacked and permit the stapler to be dismounted from the tape dispenser and rested for separate use on a flat surface in a stable condition.
