Small metal cups that hold 50 ml and do not care if they land on a concrete step. They chill quickly in the hand, which suits a spirit straight from the freezer, and they take a knock that would finish a glass.
Use for: spirits, cocktails, liqueurs and a short strong coffee
They stack down to almost nothing, which is why they end up in a picnic basket or a camping box rather than a cabinet. The smooth interior rinses clean in seconds and holds no smell from the last pour.
