This is something my husband recieved at a conference and he has been talking about it ever since. When we went to Germany we bought the moleskines notebooks which are very similar but he has now convereted over to these little guys. My husband is the kind of guy who is always coming up with new ideas so these little books are perfect for him to jot down what he is thinking. They contain 48 pages of graph paper and are the perfect size to tuck in your back pocket and carry with you at all times. I think I am going to buy some to keep track of my grocery list.
