The four-color, multi-tray BOX4BLOX is designed to conveniently sort and store LEGOs. Children and parents can simply place the pieces through the top, and they will be sorted through a series of trays with different-size grids so that the largest pieces remain on the top tray and the smallest fall through to the bottom. The product is made from quality ABS plastic and, when assembled, forms a 10.25” cube capable of storing up to 1,700 LEGOs.
