It’s a thing, the mug vs. cup and saucer…. Anyway, here’s a large cup and saucer in a ‘diner weight’ thickness (so not for those bone china lovers) and of a chunky nature. Beautiful brown glossy glaze on the outside and a white interior. It could be ‘the one’.
It holds 400ml. Cup diameter 11.5cm, saucer diameter 17cm. That should do it.
