Do you know if any of these sinks are more squared off than he others rather than having rounded corners?

We do offer two different collections of fireclay sinks. First one, Nantucket collection, features 10mm radius corners that create a more contemporary feel, ideal for transitional kitchens. The second one, Cambridge collection, has rounder corners of 40mm, for a more traditionnal touch.
