Abstract: A modular storage system including at least one storage cube and at least one connector plate. The at least one storage cube has a body defined by a plurality of side walls and a base wall about an internal chamber. At least one of the side walls or the base wall includes a plurality of peg holes extending through the respective wall in a given pattern. The at least one connector plate has a planar body with opposed first and second surfaces. At least the first surface has a plurality of pegs extending therefrom in a pattern complementary to the given pattern such that the at least one connector plate is connected to the at least one storage cube by positioning at least a subset of the plurality of pegs extending from the first surface into respective peg holes on the at least one storage cube.

Abstract: Marking instrument having a cap with a sound producing apparatus mounted therein. The sound producing apparatus includes a sound generating electronic member along with a switch and an optional button for controlling the mode of operation of the switch for determining whether the sound and/or music is generated thereby. The sound producing apparatus is retained within the cap between an intermediately positioned shoulder member and a retaining ring extending into the upper opening of the cap. The retaining ring defines an orifice through which the button member or switch means of the electronic member may extend. The retaining ring is preferably formed as a single integral member with a clip for facilitating mounting thereof with respect to the marking instrument cap to facilitate retaining of the clip member extending longitudinally along the cap of the writing instrument as well as holding the retaining ring within the opening of the cap for fixedly holding the sound producing apparatus therein.
