The Luna Collection is inspired by farmhouse decor. Each item in this collection is crafted in brown stoneware clay. The shale color combo features a semi matte gray with bronze accents. Each piece is handmade on the potter's wheel and mixes nicely with work from the Sandstone Collection. All of my work is handmade by me therefore subtle variations exist making each piece truly one of a kind. This mug is approximately 3.5 inches tall by 3.5 inches wide and comfortably holds 16 ounces of your favorite beverage. Microwave and dishwasher safe however hand washing prolongs the life of your handmade pottery.
