To ensure the longevity of the Mempo leather half-mask, the material should be cleaned regularly with a soft cloth made of natural fibers and distilled water or special leather care products. It is important to protect the leather from direct sunlight to prevent fading and to avoid contact with harsh substances such as oils or perfumes. Furthermore, the mask should not be immersed in water, and any dirt should always be removed immediately without rubbing any one spot vigorously.
