A compartmented, stackable and nestable system bin includes a bottom having a rear wall, opposed end walls and a front wall integrally connected thereto. A plurality of spaced divider walls separate the bin into a plurality of compartments. A plurality of notches are formed in a top of each of the divider walls and the end walls and a plurality of grooves are formed in the underside or bottom of each of the compartments with sets of notches on the top of the bin being in vertical alignment with sets of grooves on the bottom of the compartments. The notches of a system bin receive a pair of dowels which support an upper system bin of identical construction when the upper system bin is in stacked relation thereon and the grooves of a system bin receive a pair of dowels positioned in notches on a lower system bin of identical construction when the system bin is in stacked relation on the lower system bin.
