Created exclusively for our Colectivo Artist Series, these mugs are hand made of stoneware, which is more durable than conventional ceramics. It's fired longer and hotter - the mugs spend 34 hours in the kiln and reach over 2200 degrees F. Misewell has a passion for designing well-made objects that are not only beautiful and functional, but ethically and sustainably produced. Established by brothers Vincent & Paul Georgeson, everything is hand-crafted locally in Milwaukee. Visit misewell.com for more timeless goods, handmade in the USA. This item is a webstore exclusive.
