How should I care for my kneadable eraser to ensure its longevity and effectiveness?

To care for your kneadable eraser, store it in a clean and dry place when not in use. Avoid exposing it to extreme temperatures or direct sunlight. Knead it regularly to keep it soft and pliable. If it becomes dirty, gently knead it until the dirt is absorbed. Replace it when it becomes too stiff or loses its effectiveness.
