A stackable berry container comprises a bottom wall, a pair of opposing side walls, and first and second opposing end walls. Each of the first and second end walls forms a respective set of small vents spaced along the lengths of the end walls adjacent the bottom wall. Each of the first and second end walls further forms a respective large opening above the respective set of small vents. Each of the first and second end walls includes a bowed inner panel and an outer panel hingedly connected to each other along a rigid convex-shaped ledge. Each of the side walls including an inner panel and an outer panel hingedly connected to each other along an upper transverse edge. A first pair of minor flaps extends from opposing ends of the inner panel of one of the side walls and a second pair of minor flaps extends from opposing ends of the inner panel of the other of the side walls. One of the first pair of flaps and one of the second pair of flaps are captured between the inner and outer panels of the first end wall. The other of the first pair of flaps and the other of the second pair of flaps are captured between the inner and outer panels of the second end wall.
