A child proof metal tin box is designed to be difficult for children to open. The box typically has a latch or lock that requires an adult-sized hand to open. The box may also have a safety latch that can only be opened with a key. The box is usually made of durable metal, such as steel or aluminum, and is designed to be resistant to tampering. The box can be used to store items such as medications, cleaning supplies, and other dangerous materials.
