Butter KeeperWe can't get enough of this handcrafted ceramic french butter keeper. It holds approximately 1 2 cup of butter at room temperature for 7 14 days so you can always have soft, spreadable butter on hand! To get the best results, simply add a quarter of the way with water into the butter keeper with butter stick inside. This ensures the butter levels out smoothly, making it easier to use. Each piece is unique and varies slightly in size and shape.
