Purchasing this mace head generally requires a minimum age of 18, as it is a bladed weapon (proof of age via ID card is necessary). To protect the cast iron from corrosion and rust, the product should be stored in a dry place and regularly rubbed with a care oil (e.g., Ballistol or cooking oil) or a special care paste. Additionally, a protective film of matte clear lacquer or metal protective lacquer can be applied to seal the surface long-term.
