A modular container or bin with preferably four identical sidewalls held in place by four identical corner posts, with the sidewalls and corner posts both connected to a common base palette. The sidewalls are removably connected to the corner posts by interlocking slip joints. This slip joint configuration also removably connects the sidewalls to the base palette. The corners are secured to the base palette using four plastic bolts. The base palette has cutouts, to define feet and to provide for forklift (or other lifting devices) arm access in at least two directions. The sidewalls can also be designed for lifting by a claw lifting apparatus. The corner posts include a notch to allow cables to be secured during transportation. The container is designed primarily for the storage and transportation of agricultural products, though other uses are also possible.
