My first try at making a Book Safe

I had someone ask if I could make them a book safe... this is my first try at it! and unless I can find an easier way to cut the pages out, it may just be my last. lol 

You never know until you try, and try I did. 

The book is 9 1/2" x 7 1/2"
the inside is 7 1/2" x 5 1/2" and nearly an inch deep. 

What do you think?
