I'm a huge bookworm, and normally the thought of cutting up a book sounds horrible to me, but these hollow book safes from Hollow Book Co are so cool! Based out of NYC, creator Richie, hollows out each book by hand to recycle a book into an actual safe. He hollows out different shapes into the pages of each book, and then keeps the pages together using a clear base that makes the pages hold their shape. You can hide money, makeup, and all sorts of other trinkets inside. I adore all things Harry Potter, so I saw that they have HP book safes and was super excited. I got one and it looks even cooler in person.
The detail is really great, and Richie even puts a magnetic closure just inside the front page so that the book has a bit of a snap closure and the lid doesn't open as easily. You could keep this book on your shelf and no one would even know that it's hiding some jewelry or cash. Really fun! He makes safes out of all types of books too, so there is pretty much something for everyone.
The prices are great too, every book is under $70, with most being around $49! You can check out the entire collection of hollow book safes from Hollow Book Co on Etsy at http://www.etsy.com/shop/HollowBookCo
