The sub-oval lower part of the flask survives. One side bears a relief-moulded crown surrounded by an oval border of two ridges. The angled outer edge of the ampulla is decorated with a moulded pattern of parallel ridges and interspersing grooves. A curve of this design also frames the base of the crown, and the remnant of a further, horizontal band is visible at the broken top edge. At this point there is also a squashed loop handle, one of an original pair. The design on the other side is in the form of a scallop shell (the symbol of pilgrimage). The effect of the shell is achieved through the use of numerous parallel grooves and ridges which are narrow at the top and gradually widen towards the outer edges, where they also curve. The artefact measures 31.4mm long, 26.7mm wide and 4.9mm thick. The weight is 13.64g.

Ampullae, or holy water flasks, were common pilgrim souvenirs in the Medieval period. Although in use from the last quarter of the 12th century, these smaller, robust examples with generic designs probably date from the later Medieval period (Spencer 1990: 58).
