I bought this for my 10 year old son, since he was looking for something that he could put his "treasures" in to keep them away from his brothers and sisters, and this worked out perfectly. It has a simple number combination lock on it, that is easy enough for him to manage, while still keeping out his siblings. The box is solid and well made, and is something that I would buy for myself if I had a need to keep my things safe. It's small enough to take it with it, but can hold a fair amount inside. It's definitely worth purchasing.
