A safe is a secure storage container designed to protect valuable items, documents, or cash from theft, fire, or damage. Safes come in various sizes and types, including wall safes, floor safes, and portable safes, each serving different security needs. They often feature locking mechanisms such as key locks, combination locks, or electronic keypads. Many safes are built with fire-resistant materials to safeguard contents from extreme heat. Some models are also waterproof, providing additional protection against flooding. Common items stored in safes include jewelry, important documents, and cash, ensuring peace of mind for their owners.
