First off let me say when they say extra small they do mean extra small. These are smaller than my iPhone. They are just slightly bigger than my credit cards. If you want a notebook you can always keep with you for quick thoughts and notes, without adding more bulk this is for you! If you are looking for a diary or journal this is probably not for you. If you have an EDC mindset buy these. Don't even think about it. It'll be one of the best $5 you've spent. If you write a lot then this probably isn't for you. Maybe as a backup notebook but not enough to be a primary for a writer or artist. Know which Moleskines are for who. If this one matches you buy it. Quality wise you won't be disappointed.
