Each mug starts with a hand stamped slab so each and every one is different. They’re then constructed by hand with a textured pattern inside, and glazed so each cloud melts. The handle texture feels solid in your hand. These are dishwasher safe and hold a 12oz of liquid, so caffeinate to your hearts content, leave some room for a generous splash of whiskey, bobble of marshmallows or fluff of whipped cream. Or just have some soup. The angled rim means everything will roll right off with no drips. NO ONE likes a dribble cup.
