You will receive Cape Wrath Oysters packed in a traditional wooden punnet, with woodwool to reduce movement during transport. The punnet will be inside a polystyrene outer, with gel-packs to help keep the oysters cool. Put the punnet in the fridge on arrival. Like most perishables, oysters are best consumed within a few days of arrival, but they can have a good long shelf life provided you keep them cool and they remain shut.
