Shamrock MugA white stoneware mug, wheel thrown and lovingly adorned with a hand painted shamrock. You'll find a wee heart at the bottom of every mug for a little love. With an approximate 10oz capacity, its perfect for enjoying a good cuppa. Sarah, the creator of Ertha Pottery, crafts each piece from start to finish. Due to the handmade nature of her work, slight variations between products are to be expected.
