I spotted a post over at Black*Eiffelabout these beautiful puzzle books. They are gorgeous, small enough to pop into your handbag and stylish enough to pull out whenever you have a few moments to fill.
And even though Brain Training and the Nintendo DS are all the rage at the moment I much rather have a paper product in my hands.
These books are created by the Puzzle Society and can be bought here. They would be a really great gift for anyone.
