Made by Kilner, this glass butter bell offers a simple, traditional way to keep butter fresh and spreadable at room temperature. The clever design creates an airtight seal using water, preserving flavour and texture without refrigeration.
To use, pack softened butter into the lid and add a small amount of cold water to the base. The seal keeps butter fresh for up to a week—just refresh the water every few days.
A practical, time-tested solution for everyday use.
