The original "BOX-4-BLOX" four level plastic storage tray case.
Use to sort and organize your Lego blocks or repurpose for something else. Well constructed and durable!
Measures 10 x 10 x 10 inches.
Great condition! Each colored tray has a different size grid so that the smallest pieces fall to the bottom, next larger size pieces stay in the third tray, next larger stay in the second tray while the largest stay in the top tray.
