An improved stackable storage tray has a flat bottom wall with a generally U-shaped recess formed therein, a pair of end walls with a bar extending therebetween for manually transporting the tray, a pair of outwardly sloped side walls, and a plurality of dividers extending between the side walls and upwardly extending divider walls forming a plurality of sub-compartments. The improvements include a pair of spaced generally right angled ledges on the end walls which lie in a horizontal plane with top edges of the side wall, sub-compartment dividers, and a divider edge formed by the upstanding divider walls for supporting an upper tray stacked thereon; a plurality of bosses on the bottom wall providing support feet for the tray; and drain holes in the bosses and in the sub-compartments dividers for removing any liquid trapped in the sub-compartments.
