This Progressive Butter Dish is the ideal way to store your butter. The butter keeper features a lid which creates an airtight seal to keep your butter fresher for a longer period of time and also helps reduce odor absorption from other foods in your refrigerator. It also has handy printed measurements on its base for you to use as you cook or bake, along with ridge details on the lid to mark your butter for easy portion control. The dish can accommodate both shorter wide sticks of butter and longer narrow ones too. Made from Polypropylene and TPE.
