Stunning design by Keith Brymer-Jones. Hand-finished with the symbol of National Trust pressed into each mugs base alongside Keiths makers mark, the Pebble Grey colour of the traditional, wash glazed upper has a translucent quality that juxtaposes with the matt, uncoated finish of the exposed ceramic base. Like the places in their care, the official National Trust mug range is intended to be used and enjoyed by current & future generations, so every mug is dishwasher & microwave safe.
