Book Safe

This dictionary will definitely not help you learn Hebrew - or any other language - but you can keep your valuables and money safe in it, so one day, who knows, you can join a Hebrew class. This book safe with the boring cover has enough room for a good amount of jewelry and will remain unnoticed in your bookshelf, blended with your other real books.
If you are looking for inexpensive security, this could well be it. It's very realistic looking and no one would ever tell whether it’s a book or a safe. It has a hiding metal space that can hold money, cards, packet of cigarettes, small objects and more. Just make sure you don’t lose the key and you’ll have a discreet safe for small valuables.
