Butter Bells are a French way of holding butter on the counter. You fill the bell with the soft butter and put a bit of water in the canister. When the butter is turned upside down into the canister of water it preserves the butter while being left out of the refrigerator. Please note : some of the bigger bells can hold up to 2 sticks of butter. *All of Twiddle T's ware's are Dishwasher safe, Microwave safe and Oven safe.
