Made from stoneware, this mug is durable and able to withstand daily use. It is worth bearing in mind however, that all handmade products come with a degree of fragility, especially due to the size of the handles on these mugs, they can become more susceptible to getting knocked and breaking off so use it with care. It is also recommended to handwash this product as while it will survive the occasional dishwasher, repeated use will over time deteriorate the glaze and adds extra risk for things knocking around and chipping.
