The item
Model 702.758.61
KALLAX is IKEA's open grid cube shelf, shown here in the large 4-by-4 size. It flat-packs into a square carton about 60 by 12 by 60 inches, the biggest of the KALLAX range, so it is bulky and awkward even though it is only a foot thick. Bring the flat box in and assemble the grid in place.
