This is a brand new shape for me, and I absolutely love it. The bulbous shape with a closed top keeps my coffee nice and warm and the thumb rest just lovely in my hand. I've tried variations of this shape several times over the years, but I've finally found one that feels just right. I've added a ring around the mug that makes the glazed look fluid and drippy. There will be variations in each mug, but the blue glaze is the same, and the variations are what make them so unique! Holds bout 12-14 oz.
