Crafted in Mexico, the design on these awesome mugs is based on the work of the late artist and ceramicist Mara who studied in London and Italy. Her work is now carried on by her family and the loyal artisans who apprenticed under her. Each mug is etched and painted by hand so no two are alike. The mugs are fired at high temperatures using lead free glazes, so they are as functional as they are beautiful. Mugs are both microwave and dishwasher safe. Extra -large handle is comfortable to hold and the thick walls hold in the heat so you can enjoy a leisurely morning over your favorite hot beverage. 16 ounce mugs are 3 ¾” in diameter and 4” tall.
