Healthy Porcelain Material - Unlike plastic materials, our butter dish is made of durable porcelain. Porcelains are free of toxins and chemical ingredients. So it is safe for your environment and family. This Butter container is chip-resistant and more sturdy than stoneware. No Need for An Extra Butter Knife & Cutting Board - The knife on the butter lid groove is made of 304 stainless steel. You can use it to cut butter and spread bread. The bamboo lid can be used as a cutting board. So convenient and useful! Bamboo Lid with Sealing Ring - The butter dish lid with a sealing ring helps keep your butter sticks fresh in the refrigerator and do not mix the taste of other foods. It can also effectively prevent the spoilage of foods. Easy to Clean - The butter dish is made of porcelain, so it can clean with hot water and soap easily. You can also put it in the dishwasher to clean. Notice: do not put the lid into the microwave, dishwasher or oven. The lid can remove easily for better washing.
