If you carry your notebook around with you (in your bag, thrown onto the back seat of the car etc) you’ll know the importance of sturdiness. The last thing you need is a cover that is dog-eared or scratched up or ruined. Not only does it make your notebook look tatty, it also kills inspiration.
You needn’t worry about such things with these notebooks. They’ve been designed for rough and rugged use. You can take them anywhere and they’ll withstand the toughest treatment.
(While Moleskine’s don’t appear on this list their omission is definitely not a snub. I use Moleskines all the time and I think they are superb. I wanted to showcase some other notebooks – perhaps ones you’ve never heard of – because it’s a big, wide world out there and it’s full of new notebooks to discover.)
