A shelving system includes a shelving unit with at least one open sidewall that provides access to an interior of the shelving unit and one or more inserts that can be selectively connected to and disconnected from an interior of the unit in order to compartmentalize the interior of the unit. This enables a user to separate, sort and store items in the interior in an orderly fashion. The at least one open sidewall also serves to display the items stored in the unit. The shelving unit can be attached to a supporting wall in order to be located at desirable height to facilitate storage and display of the items stored therein.
