The jars from 12 Wa 258 are globular to slightly elongated in form with moderately constricted necks, prominent, rounded shoulders and rounded bases. Exterior surfaces are marked with closely spaced cord impressions which are applied vertical to the rim and cover the exterior surfaces except for the rims and lips. Necks are decorated with incised oblique cross-hatching. Rims are wedged or collared. Short, plain vertical lines, which appear to be impressions rather than incisions, occur on the peak of the wedges as well as exterior lips.
Interior decoration is restricted to the lip and neck of each vessel.
Plain vertical impressions occur around the interior surface of the lips. Below this point the interior of the necks are cross-hatched with oblique lines like those noted for the exterior surfaces.
