Keep your butter soft, fresh and well-preserved with these stoneware Butter Keeps. Designed to be stored on the counter or table, the Butter Keeps are a 17th century French invention that ensures that your butter will remain pathogen free as it stays soft for easy spreading. Simply place butter in the inverted top to shield it from light and oxygen, and add water into the base to create an airtight seal. Available in flour and matte black colors.
