Bluish-green stemmed cup with a vertical rim, the lip inclined inwards, thickened and rounded, the sides taper slightly downwards to near the base of the body where they curve more sharply to meet the stem; a short cylindrical stem and splayed, folded footstand with a tubular rim and lower fold pushed up to the top of the stem from below. The cup is decorated from the rim with closely-set curving mould-blown ribs, running clockwise, at first horizontally and then turning downwards and fading out towards bottom of body.
The cup is blown, the ribbing is pre-moulded on a gob and expanded and twisted during inflation; the stem and footstand are tooled from the same gob as the body; no pontil-mark.
