To prevent cracks in the leather belt with a wolf's head buckle, it should be treated regularly with special care products such as leather balm, leather grease, or leather oil to keep the leather supple. Ideally, store the belt loosely rolled up or hanging in a dry, dark place to prevent creases and protect it from direct sunlight and heat sources that could dry out the material. Cleaning should only be done with a slightly damp cloth and without harsh cleaning agents.
