Incomplete cast copper alloy button and loop fastener. The head is circular, slightly domed and decorated with four pointed oval petals around a central circle, with a pellet in each field between the petals. This is all in reserve metal. The recessed fields between would once have contained enamel however only a small patch of blue remains in the field outside the petals.
There is an incomplete loop extending from the reverse, which is broken as it splits to form the loop..
