Abstract: A storage unit has a top, a bottom, and a carousel upon which the bottom rotates thereupon. A plurality of drawers is disposed symmetrically between the bottom and the top. Each drawer has a pentagonal shape having a front wall, a pair of front side walls each of which extends from the front wall and are parallel to each other, a pair of back side walls each of which extends from a front side wall and converges towards an other of the back side walls and a back wall attaching to each of the back side walls. Each back side wall of one drawer contacts an adjacent side wall of an adjacent drawer and the back walls of the drawers define a space.
