Coffee and tea lovers, rejoice! Crafted from smooth, marbled soapstone, this mug will make your morning ritual even better. The properties of soapstone, a metamorphic rock, naturally help hot liquids stay hot for extended periods. (Fun tip: preheat the mug with hot water or heat it on a stove before adding your favorite hot beverage!) No two pieces of soapstone are exactly alike, making it completely unique and rare.
