I use these in my home office to store ammo cans and accessories in. They lock to keep out kids and curious entities. It is a effectively a gun accessory cabinet (not gun safe) that blends in to an office. If it says HON it is not a thin metal cabinet. These usually cost ($400 and up) way more than you would pay for this use but these look like they are going for around $100. I was looking up sources for replacement keys on the internet when I came across these.
