These guys are giant! They're about five and a half to six inches tall and hold about thirty ounces filled all the way to the rim. They're made of a half porcelain half stoneware clay that's locally sourced and glazed with a matte glaze that's a lightly speckled buttery color on the outside and lavender on the inside. Where the glaze doubles over it creates a lovely blue color on the rim of the mugs. They are dishwasher safe but hand washing is recommended.
