The present application relates to a self-contained, hand-held dispenser for providing a user-determined amount of a substance. The hand-held dispenser includes a hand-squeezable reservoir that is structured to enable the dispenser to be readily stackable with other such dispensers. The hand-help dispenser further includes a dispensing portion that protectively seals a substance stored in the reservoir and is further configured to control dispensation of the substance for a user-predetermined purpose, such as for consumption of the substance. Further still, the dispenser includes a cover having a first and a second position for providing access to the reservoir and/or dosing a substance contained therein.
