Embodiments include container assemblies for presentation of contents. In one example, a container assembly for writing instruments may include a slideable platform with a threaded hole configured to operably receive a threaded post therethrough, a housing having at least one guide rail, a manually rotatable base configured to rotate, such that rotation of the manually rotatable base moves the slideable platform within the housing along the at least one guide rail, and at least one platform stopper configured to prevent the slideable platform from advancing past the pre-determined height, wherein the pre-determined height is selected such that the writing instruments are retained by the housing in the container assembly when the slideable platform is in contact with the at least one platform stopper.
