Paraic Poil a prolific Irish dry stone wall builder who lives on Inisheer island showed me this cup he was given with a photo of a section of curved wall he built. It wraps almost around the entire cup. We saw the wall earlier in the day . It’s quite tall and like many of his walls very impressive. I think he should get a whole set of cups made up with other sections of walls. I’m guessing he’d have no trouble stacking them on his shelves.
