A Numerical Inventory Control Device for holding and then dispensing one or more items contained within the device wherein the items are gradually moved from the back toward the front of the device by a moving slideable pusher which is biased against a constant force coil spring contained in a dispenser housing attached at the back end of the pusher and wherein one end of the coil spring is affixed to the dispenser housing wherein, when product, near the front of the housing, is removed the constant force spring will cause the pusher to advance the next product toward the front for dispensing purposes. An inventory indicator sheet, essentially in the form of an endless belt, is attached at one end to the front side of the pusher and at the other end to the rear of the pusher and has one or more rows of numbers thereon, which indicate, at the front of the device, the quantity of units remaining in the dispensing device.
