Based on the classic French beurrier, our marble butter crock keeps butter soft & spreadable without refrigeration. The natural marble looks beautiful on your table or countertop, revealing subtle grey veining & a smooth hand-polished finish. Holds 2.5 oz. butter (about half a stick) packed into cup on underside of lid. Fill the crock with cold water to keep butter soft—without refrigeration—for 3 to 5 days. Change the water to keep butter fresh. Hand made of solid white natural marble. Polished by hand to a lustrous finish. Natural variations in marble make each piece unique.
