Don't judge this book by its cover! The Hidden Real Book Lock Box from Barska is designed to provide a safe, reliable, and low-profile hiding place for your most valuable possessions, documents, jewelry, or cash. While the interior walls are made of steel, the outside appears as a real Pride and Prejudice book. It blends in naturally with the rest of your library on a bookshelf, making it virtually impossible to detect, and creating a safe hiding place for your valuables in plain sight.
